Q: Is it possible to display a vector (polygon) map so that colors are chosen based on an attribute column (not the "cat")? I assume this can be done through v.reclass with a rules file, but am hoping there is a simpler way.
A: For random colorization enjoy the -c flag. For precise colorization add a column containing RRR:GGG:BBB values (use v.db.update to quickly populate it) and then use the -a flag of d.vect.
