White petals are interesting to paint, because in watercolor white paint is not used. What really is painted are the shadows that give the white object visual substance. Ah, but then what color are the shadows? That is the job of the artist to determine, and then perhaps, to embellish. This crisp white little flower had a lot of blue in it. The painting also has an extra feature: my fingerprint accidentally got on the lower right petal. That's one of the things about watercolor. There is not much you can do about that sort of thing. Oh well. Gives it character, maybe?
