CRIB for managing color tables and line colors and taking control of colors in tplot
ROUTINES:
initct : Wrapper for loadct2 and loadcsv. Works the same way as loadct2 and loadcsv,
but provides access to both sets of color tables. Provides keywords for
setting line colors. The previous routines still exist and can still be
called as before, so there's no need to modify any code unless you want to.
showct : Display the current color table or any color table with any line color scheme.
revvid : Swaps the values of !p.background and !p.color.
line_colors : Choose one of 11 predefined line color schemes, or define a custom scheme.
get_line_colors : Returns a 3x8 array of the current line colors [[R,G,B],[R,G,B], ...].
Can also return the 3x8 array for any line color scheme.
See the headers of these routines for more details.
OVERVIEW:
Chances are you have a TrueColor display that can produce 256^3 = 16,777,216 colors by
adding red, green and blue levels, each from 0 to 255. Tplot and many associated
routines use a color table, which is a 3x256 array consisting of a small subset of the
possible colors. Tplot reserves eight colors: one for the foreground color, one for the
background color, and six for drawing lines. The rest make up the color table:
Color Purpose Modify With
--------------------------------------------------------------------------
0 black (or any dark color) initct, line_colors
1-6 fixed line colors initct, line_colors
7-254 color table (bottom_c to top_c) initct
255 white (or any light color) initct, line_colors
--------------------------------------------------------------------------
Colors 0 and 255 are usually associated with !p.background and !p.color. For a light
background, set !p.background = 255 and !p.color = 0. Do the opposite for a dark
background. Use revvid to toggle between these options.
There are many possible color tables, because each table uses only 248 out of more than
16 million available colors. The standard catalog has table numbers from 0 to 74, while
the CSV catalog has table numbers from 0 to 118. These ranges overlap, so we need some
way to separate them. I chose to add 1000 to the CSV table numbers, so CSV table 78
becomes 1078, etc. There is also substantial overlap in the tables themselves:
Standard Tables CSV Tables Note
----------------------------------------------------------------
0 - 40 1000 - 1040 identical or nearly so
41 - 43 1041 - 1043 different
44 - 74 1044 - 1074 identical
N/A 1075 - 1118 unique to CSV
----------------------------------------------------------------
When tables are "nearly identical", only a few colors are different. The nearly identical
tables are: [24, 29, 30, 38, 39, 40] <-> [1024, 1029, 1030, 1038, 1039, 1040]. So, apart
from a few slight differences, there are 122 unique tables.
As of this writing, there are 11 predefined line color schemes:
0 : primary and secondary colors [black, magenta, blue, cyan, green, yellow, red, white]
1-4 : four different schemes suitable for colorblind vision
5 : same as 0, except orange replaces yellow for better contrast on white
6 : same as 0, except gray replaces yellow for better contrast on white
7 : https://www.nature.com/articles/nmeth.1618, except no reddish purple
8 : https://www.nature.com/articles/nmeth.1618, except no yellow
9 : same as 8 but permuted so vector defaults are blue, orange, reddish purple
10 : Chaffin's CSV line colors, suitable for colorblind vision
More schemes can be added by including them in the initialization block of get_line_colors.pro.
Always add new schemes at the end of the list, so you don't break anyone else's code. It's
helpful if you can add a note about your scheme.
Use showct to preview any color table with any line color scheme.
Tplot has been modified to use initct and line_colors, so you can set custom color tables
and line color schemes for individual tplot variables using options.

return
Place the following lines in your idl_startup.pro to initialize your device and color
table. Of course, you can choose any of >100 color tables (reversed if desired), any of
the predefined line color schemes, or completely custom line colors. This example sets a
dark background, but many people prefer a light background.
evice,decompose=0,retain=2 ; specific to MacOS (settings for other OS's might be different)
; decompose=0 --> use color table with TrueColor display
; retain=2 --> IDL provides backing store (safest option)
nitct,1074,line=5,/rev,/sup ; define color table and fixed line colors (suppress error message)
p.background = 0 ; use tplot fixed color for background (0 = black by default)
p.color = 255 ; use tplot fixed color for foreground (255 = white by default)
To use color tables with the Z buffer, do the following:
et_plot, 'z' ; switch to virtual graphics device
evice, set_pixel_depth=24, decompose=0 ; allow the Z buffer to use color tables
Change the color table at the command line. This does not alter the line color scheme,
which is persistent until you explicitly change it.
nict, 1091
Select a new color table and line color scheme at the command line.
nitct, 43, line=2
Change line colors without otherwise modifying the color table.
ine_colors, 6
Swap !p.background and !p.color
evvid
Use gray instead of white for the background, which looks better in some situations.
The default gray level is [211,211,211].
evvid, /white ; if needed
ine_colors, 5, /graybkg
Use a custom gray level for the background.
evvid, /white ; if needed
ine_colors, 5, graybkg=[198,198,198]
Poke arbitrary RGB colors into indices 1 and 4 of the current line color scheme.
ine_colors, mycolors={ind:[1,4], rgb:[[198,83,44],[18,211,61]]}
Use a fancy rainbow-like CSV color table with line colors suitable for color blind people.
CSV color tables encode intensity first and color second, which is closer to how humans
perceive colors. Reverse the table, so that blue is low and red is high.
nitct, 1074, /reverse, line=8
See a catalog of the many CSV color tables. (Note: loadcsv is not usually called directly.)
Remember that you have to add 1000 to CSV color table numbers.
oadcsv, /catalog
Display the current color table with an intensity plot.
howct, /i
Display any color table with any line color scheme -- DOES NOT modify the current color table.
howct, 1078, line=8, /i
howct, 1091, line=5, /reverse, /graybkg, /i
Set a custom color table and line color scheme for any tplot variable. This allows you
to use multiple color tables and/or line color schemes within a single multi-panel plot.

Disable custom color tables and line colors for a tplot variable.
ptions, var1, 'color_table', -1
ptions, var1, 'line_colors', -1
Set color and line style for constants. If there are fewer colors than values, then
the colors are cycled as needed. There can be only one line style per variable.

FUNCTION get_line_colors
Get the current line colors, or line colors specified by input and/or keyword.
Returns the result as an array of 24 (3x8) RGB colors: [[R,G,B], [R,G,B], ...].
This DOES NOT alter the color table or assert any new line colors. To do that
you would pass the result of this routine to line_colors, initct, or as an
option for a tplot variable.
To set custom line colors for any tplot panel do one of the following:
lines = n ; where 0 <= n <= 10
options, varname, 'line_colors', lines
lines = get_line_colors(line_clrs, KEYWORD=value, ...)
options, varname, 'line_colors', lines
To disable custom line colors for a tplot variable:
options, varname, 'line_colors', -1
USAGE:
mycolors = get_line_colors([line_clrs] [, KEYWORD=value, ...])
INPUTS:
line_clrs : This input is optional. Can take one of two forms:
(1) Integer array of 24 (3x8) RGB values: [[R,G,B], [R,G,B], ...] that defines the
first 7 colors (0-6) and the last (255). Tplot assumes the following:
Index Purpose
--------------------------------------------------
0 black (or any dark color)
1-6 fixed line colors
7-254 color table (bottom_c to top_c)
255 white (or any light color)
--------------------------------------------------
Indices 0 and 255 are associated with !p.background and !p.color. For a light
background, set !p.background = 255 and !p.color = 0. Do the opposite for a
dark background. Use revvid to toggle between these options.
(2) Integer that selects one of the predefined color schemes:
0 : primary and secondary colors [black, magenta, blue, cyan, green, yellow, red, white]
1-4 : four different schemes suitable for colorblind vision
5 : same as 0, except orange replaces yellow for better contrast on white
6 : same as 0, except gray replaces yellow for better contrast on white
7 : see https://www.nature.com/articles/nmeth.1618, except no reddish purple
8 : see https://www.nature.com/articles/nmeth.1618, except no yellow
9 : same as 8 but permuted so vector defaults are blue, orange, reddish purple
10 : Chaffin's CSV line colors, suitable for colorblind vision
If there is no input and no keywords are set, this routine returns the current
line colors.
KEYWORDS:
COLOR_NAMES: String array of 8 line color names. You must use line color names
recognized by spd_get_color(). RGB values for unrecognized color names are
set to zero. Note that named colors are approximated by the nearest RGB
neighbors in the currently loaded color table. This can work OK for rainbow
color tables, but for tables that primarily encode intensity, the actual
colors can be quite different from the requested ones.
MYCOLORS: A structure defining up to 8 custom colors. This provides an alternate
method of poking individual custom colors into color indices 0-6 and 255.
{ ind : up to 8 integers (0-6 or 255) , $
rgb : up to 8 RGB levels [[R,G,B], [R,G,B], ...] }
The indicies (ind) specified in this structure will replace one or more of the
current line colors. You are not allowed to change color indices 7-254, because
those are reserved for the color table. Indices 0 and 255 allow you to define
custom background and foreground colors.
GRAYBKG: Set color index 255 to gray [211,211,211] instead of white. See keyword
MYCOLORS for a general method of setting any line color to any RGB value.
For example, GRAYBKG=1 is equivalent to MYCOLORS={ind:255, rgb:[211,211,211]}.
To actually use this color for the background, you must set !p.background=255
(normally combined with !p.color=0).

PROCEDURE: initct
PURPOSE:
Wrapper for loadct2 and loadcsv. Calls the appropriate color table
routine based on the requested table number:
table numbers < 1000 (currently 0-74) : use loadct2
table numbers >= 1000 (currently 1000-1118) : use loadcsv
There is substantial overlap between the standard and CSV tables:
Standard Tables CSV Tables Note
----------------------------------------------------------------
0 - 40 1000 - 1040 identical or nearly so
41 - 43 1041 - 1043 different
44 - 74 1044 - 1074 identical
N/A 1075 - 1118 unique to CSV
----------------------------------------------------------------
When tables are "nearly identical", only a few colors are different.
The nearly identical tables are: [24, 29, 30, 38, 39, 40] <->
[1024, 1029, 1030, 1038, 1039, 1040]. So, apart from a few slight
differences, there are 122 unique tables.
Keywords are provided to define fixed colors that are used for lines
(1-6), and the background and foreground colors (0,255).
** Once set, these fixed colors are persistent until explicitly changed.
Use line_colors.pro to change the fixed colors without affecting the rest
of the color table.
Use get_line_colors() to return a 3x8 array containing either the current
line colors or custom colors specified by input and keyword. This can be
used to set custom line colors for a tplot variable. See get_line_colors
for details.
USAGE:
initct, colortbl [, KEYWORD=value, ...]
INPUTS:
colortbl: Color table number. If less than 1000, call loadct2
to load one of the standard color tables. If greater
than or equal to 1000, call loadcsv to load one of
the CSV color tables. Required. No default.
KEYWORDS:
REVERSE: If set, reverse the color table (indices 7-254).
LINE_CLRS: Defines custom line colors. Can take one of two forms:
(1) Array of 24 (3x8) RGB values that define 8 fixed colors
(the first 7 and the last) of the color table:
LINE_CLRS = [[R,G,B], [R,G,B], ...].
(2) Integer that selects a predefined color scheme:
0 : primary and secondary colors
1-4 : four different schemes suitable for colorblind vision
5 : same as 0, except orange replaces yellow for better contrast on white
6 : same as 0, except gray replaces yellow for better contrast on white
7 : https://www.nature.com/articles/nmeth.1618 except no reddish purple
8 : https://www.nature.com/articles/nmeth.1618 except no yellow
9 : same as 8 but permuted so vector defaults are blue, orange, reddish purple
10 : Chaffin's CSV line colors, suitable for colorblind vision
See get_line_colors() for RGB values of predefined schemes.
The most recent color schemes may not be documented here.
COLOR_NAMES: String array of 8 line color names. You must use line color
names recognized by spd_get_color(). RGB values for unrecognized
color names are set to zero. Not recommended, because named
colors are approximated by the nearest RGB neighbors in the
currently loaded color table. This can work OK for rainbow color
tables, but for tables that primarily encode intensity, the
actual colors can be quite different from the requested ones.
Included for backward compatibility.
MYCOLORS: A structure defining up to 8 custom colors. These are
fixed colors used to draw colored lines (1-6) and to define
the background (0) and foreground (255) colors.
{ ind : up to 8 integers (0-6 or 255) , $
rgb : up to 8 RGB levels [[R,G,B], [R,G,B], ...] }
The indicies (ind) specified in MYCOLORS will replace one or
more of the default colors. You are not allowed to change
color indices 7-254, because those are reserved for the
color table. Indices 0 and 255 allow you to define custom
background and foreground colors.
GRAYBKG: Set color index 255 to gray [211,211,211] instead of white.
See keyword MYCOLORS for a general method of setting any line
color to any RGB value. For example, GRAYBKG=1 is equivalent
to MYCOLORS={ind:255, rgb:[211,211,211]}.
To actually use this color for the background, you must set
!p.background=255 (normally combined with !p.color=0).
A quick way to do this: revvid, /white
PREVIOUS_CT: Named variable to hold the previous color table number.
Use this to temporarily change the color table and then return
to the previous one. Tplot needs this to change color tables
on the fly.
PREVIOUS_REV: Named variable to hold the previous color reverse.
Use this to temporarily change the color table and then return
to the previous one. Tplot needs this to change color tables
on the fly.
SHOW: Show the color table in a separate window after loading.
SUPPRESS: Suppress floating overflow error in first call to window.

USAGE:
line_colors [, line_clrs] [, KEYWORD=value, ...]
INPUTS:
line_clrs : Can take one of two forms:
(1) Integer array of 24 (3x8) RGB values: [[R,G,B], [R,G,B], ...] that defines

The indicies (ind) specified in MYCOLORS will replace one or
more of the default colors. You are not allowed to change
color indices 7-254, because those are reserved for the
color table. Indices 0 and 255 allow you to define custom
background and foreground colors. For example, the following
chooses color scheme 5, but sets the background color to light
gray with a black foreground (pen) color:
line_colors, 5, mycolors={ind:255, rgb:[211,211,211]}
!p.color = 0
!p.background = 255
GRAYBKG: Set color index 255 to gray [211,211,211] instead of white.
See keyword MYCOLORS for a general method of setting any line
color to any RGB value. For example, GRAYBKG=1 is equivalent

To actually use this color for the background, you must set
!p.background=255 (normally combined with !p.color=0).
PREVIOUS_LINES: Named variable to hold the previous line colors.
Tplot needs this to swap line colors on the fly.

PROCEDURE loadct2, colortable
By default LOADCT2 uses the same color table used by LOADCT
This can be changed in 3 ways:
1) Use the FILE keyword to define a new file
2) Define the environment variable IDL_CT_FILE to point to a new file
3) Place a new color table file in the same directory as LOADCT2 that matches
the name: 'colors*.tbl'. (The last file found with file_search is used).
This routine now uses get_line_colors() to define the eight fixed RGB colors for
drawing lines and setting the background and foreground colors. All line color
keywords work as before but are now passed to that function. Please place any
new line color schemes in get_line_colors().
USAGE:
loadct2, colortable [, KEYWORD=value, ...]
INPUTS:
colortable: Color table number. Required.
KEYWORDS:
REVERSE: If set, then reverse the table order from bottom_c to top_c.
PREVIOUS_CT: Needed by tplot to change color tables on the fly.
PREVIOUS_REV: Needed by tplot to change color tables on the fly.
FILE: (string) Color table file
If FILE is not provided then LOADCT2
Uses the environment variable IDL_CT_FILE to determine
the color table file if FILE is not set.
LINE_CLRS: Integer array of 24 (3x8) RGB values: [[R,G,B], [R,G,B], ...]
If this input does not have exactly 24 elements, then a predefined set of 8 colors
will be used based on the value of the first element. Pre-defined color schemes
are currently (see code below for any new undocumented schemes):
0 : primary colors
1-4 : four different schemes suitable for colorblind vision
5 : primary colors, except orange replaces yellow for better contrast on white
6 : primary colors, except gray replaces yellow for better contrast on white
7 : see https://www.nature.com/articles/nmeth.1618 except no reddish purple
8 : see https://www.nature.com/articles/nmeth.1618 except no yellow
9 : same as 8 but permuted so vector defaults are blue, orange, reddish purple
10 : Chaffin's CSV line colors, suitable for colorblind vision
LINE_COLOR_NAMES: String array of 8 line color names. You must use line color names
recognized by spd_get_color(). RGB values for unrecognized color names are set
to zero. Note that named colors are approximated by the nearest RGB neighbors in
the currently loaded color table. This can work OK for rainbow color tables, but
for tables that primarily encode intensity, the actual colors can be quite different
from the requested ones. Included for backward compatibility.
COLOR_NAMES: Synonym for LINE_COLOR_NAMES. Allows better keyword minimum matching, if the
previous keyword can be retired. Both keywords are accepted - this one takes precedence.
MYCOLORS:
A structure defining up to 8 custom colors. This provides an alternate method of
poking individual custom colors into the fixed color indices (0-6 and 255).
{ ind : up to 8 integers (0-6 or 255) , $
rgb : up to 8 RGB levels [[R,G,B], [R,G,B], ...] }
You can also specify LINE_CLRS and LINE_COLOR_NAMES, and this keyword can make further
adjustments.
The indicies (ind) specified in MYCOLORS will replace one or more of these
colors. You are not allowed to change color indices 7-254, because those
are reserved for the color table. Indices 0 and 255 allow you to define
custom foreground and background colors.
GRAYBKG: Set color index 255 to gray [211,211,211] instead of white.
See keyword MYCOLORS for a general method of setting any line color to any RGB value.
For example, GRAYBKG=1 is equivalent to MYCOLORS={ind:255, rgb:[211,211,211]}.
To actually use this color for the background, you must set !p.background=255
(normally combined with !p.color=0).
