I don't want to sound old, but in my day, you had
to do more than put a couple of commands in a logical order
to become a hero. ;-)

Well at this point it happened what people told you to be careful
about... You overwrote the IDL rainbow colortable with the IDL grayscale
colortable.

Hi Andrew
Thanks a lot... but make a mistake!!!!!
but my result was copied rainbow palette number 13 to number 41 but
both remain in grayscale.
my command was!!!
IDL> TVLCT, r, g, b, /Get
IDL> ModifyCT, 13, 'Rainbow', r, g, b
% Compiled module: MODIFYCT.
% Compiled module: FILEPATH.
IDL> XColors
% Compiled module: XCOLORS.
% Compiled module: FIND_RESOURCE_FILE.
% Compiled module: PROGRAMROOTDIR.
% Compiled module: STRSPLIT.
% Compiled module: XREGISTERED.
% Compiled module: LOADCT.
% Compiled module: XMANAGER.
IDL> ModifyCT, 41, 'Rainbow', r, g, b
IDL> xloadct
Any Idea!!!

Yes, You have not supplied the table index parameter!
You must tell ModifyCT which table you want to modify...
Try using Help, modifyct at the command line

I think that you are not using the routine properly. You are missing the index. Did you read the documentation ?
TVLCT, r, g, b, /GET
ltab=45
MODIFYCT, ltab, 'my rainbow palette', r, g, b
PRINT, ltab
The palette will be stored in the index ltab. Next time you want to load the palette, you can do LOADCT, ltab
The magic is done !

Could you show the command that caused this error?
I have several other color tables files that I access with the FILE
keyword of [X]LOADCT and find this a quite nice way to store color tables.

Modify your palette using XPALETTE. Then, you can retrieve the RGB values with TVLCT, r, g, b, /GET and create a SAV file with these values SAVE, FILENAME='myrainbowpalette.sav', r, g, b
After that, if you want to use these same colors again, you can restore the palette RESTORE, 'myrainbowpalette.sav' and set the colors using TVLCT, r, g, b
Another option is to modify the palette using MODIFYCT. You can create your own color-palette-table or overwrite the existing one (even if this is not a good idea). If you create your table, you will have to specify the file LOADCT, FILE=file, or MODIFYCT, FILE=file
