The thread was at its max # of posts so I couldn't respond there. Thank you for the lovely compliment on my kitchen. The walls are three different shades of yellow paint - I can find the precise colors for you if you would like. I just used three shades off of the same color card at Lowes.

I painted the walls the medium color, then went back and dabbed in the lightest color with a large paintbrush, followed by the darkest color, then blended all with more paintbrush dabbing and a bit more of the medium color. I was going for a "waterfall" look, but in yellow (kinda sounds gross when described that way). It was fairly time consuming, but I got the kitchen painted in one day.
