Hi,

currently "d.vect -c" random colors is limited to 16 colors, which do
not rotate between calls. (you get the same colors every time, d.redraw
doesn't help if you don't like the results)

see display/d.vect/plot.h for current candidates.

I suggest using random color code from lib/gis/color_rand.c to do a
better job. It seems to work pretty well.


or if that won't work (too many cats to store RGB values) start with
random seed and calculate R,G,B values by some mathematical function
which will give the same answers for those 3 variables within the module
run.


thanks,
Hamish
