Orange or Yellow

I won't numb your minds with flowery names, I'll just ask, "Orange or Yellow?"

After painting the walls "Egyptian Nile" to blot out the "Falling Leaves" (I had to get my flowery names in somewhere!) we discovered that the green on the back of the bookshelves had no place in our Egyptian Nile room (it clashed.)

So I painted one bookshelf back yellow and the other orange, at Kevin's suggestion, to see which one looks better. I'm taking votes as I am feeling very indecisive about this.
