Micha,
I didn't know whether grass cared about the numeric format. I'll
lookup
the hex code to decimal code and change then in the same column (a
simple
update statement).
Something like this might help:
>printf "%d\n" 0xff
255
You'll have to split the hex string into the 3 color components,
of course.
Still for me to learn is the relation between v.colors and d.vect.
Trial-and-error learning, I suppose.
Thanks,
Rich
