Convoluted Colours

I'm trying to work on my coloured white objects piece (the white ceramic stuff in the red box) with zero luck. I'm just scared of it, I guess. Colour is this big world that I'm just dipping my fingertip in, and it's big and confusing and I have no idea what to do with it.
My figure piece didn't really feel like it was getting anywhere tonight, but I like it.
I worry that I don't know how good I am and that I don't know enough about furniture and that maybe furniture just isn't right for me and maybe I should go into something else, but what?
Huh.
