in src/include/colors.h and some other places in the code the color #define VIOLET 7 is used.
This was used with the show.color.sh script until i removed violet from
there because it is not included in the list of available colors
(defined in src/include/colors.h).
The X window driver has still a definition for violet and removes this
color from the list of available display colors (so that if you draw a
vector polygon over a raster it is always visible).
Is there any reason for not using violet?
I'd like to check in a module 'g.listcolors' or 'd.listcolors' that
returns a separated list of available colors for use in scripts.
Although i hesitate to add just another module, i think that there must
be a method to get the list of colors as hard-coding this into scripts
or tcltkgrass is bad practice.
Please tell me if there are objections and if the module should be named
g.listcolors or d.listcolors.
cu,
Andreas

No idea.... Maybe an undocumented bug?

Perhaps g.colorslist and d.colorslist would be better as the more
important word comes first (so not to confuse with g.list).
Just a suggestion.
