Individual vectors can be displayed with d.vect.line:

d.vect.line map=contours color=white catnum=-200,-100,0
d.vect.line map=contours color=128:128:128 catnum=-150,-50
d.vect.line map=contours color=green catnum=100,200

Or coloured according to a legend file with d.vect.line legend=xxxx


d.vect.area has similar options.
