I thought that since I like bright yellow as a color, this would be an easy challenge. Wrong, wrong. I started trying sherbert yellow's and pink's with my brighest yellow and they wonderfully mellowed it too much since I am trying to focus on the challenge color in the middle and have supporting colors around it. Then I tried the bright yellow's with a dark blue and lime green, but the lime ended up being too light. Finally, on to aqua and black, and this is as good as I am going to get this week I think. I like the contrast and think there is enough movement.
