The following panel items will not appear if dstool is running on a monochrome display.
The user is free to design and incorporate additional colormaps into dstool. The file $DSTOOL/colormaps/colormap demonstrates the correct format for colormaps: the first number in the file in the total number of entries in the colormap. Each entry is an integer triplet (r, g, b) which defines a color by specifying a proportion of red, green, and blue hues. Each of r, g, and b must be an integer between 0 and 255. Examples: the triple (255, 0, 0) is pure red, (255, 0, 255) is purple, (255, 255, 255) is pure white, and (0, 0, 0) is black.
