Opposites Attract

Continuing with the idea that this is a challange, I decided to pick a colorwave of opposites, or complementary colors.  If I had really wanted a challenge, I would have picked blue - orange, which I have never liked working with, but I kind of like purple - yellow, so here it is, a challange with two colors I like!  I am purposely not showing any pictures of anything else, because I don't want you to focus on an image, which a lot of us, including myself, did for Kristin's challange.  I find starting a piece with just the color choices really difficult, but that is what I want you to do here.
I forgot to add that you can use any accent colors you want to this.
