mpl.legend.RegularPolyCollection.set_facecolor

RegularPolyCollection.set_facecolor(c)

Set the facecolor(s) of the collection. c can be a matplotlib color spec (all patches have same color), or a sequence of specs; if it is a sequence the patches will cycle through the sequence.

If c is ‘none’, the patch will not be filled.

ACCEPTS: matplotlib color spec or sequence of specs
