I don't think I can vote! I tried but it is too situational. At first I thought yellow... I have never owned a piece of yellow clothing, furniture, or car in my life, but then I thought about how beautiful I find yellow birds, yellow flowers, and yellow butterflies. It's that way with all colors really, I can think of things I like colors on and things I don't care for some colors on. I guess I can't really pick out a least favorite color unless it was specific to clothing or something like that
