I'm really starting to like how this is looking now. This is so much fun mixing the colors to get the look of a "singing" grey. Today was a lot more of the same. Basically I'm using the same color combos as listed earlier. Think of the cloud blue and light peach as your lightest grey. Periwinkle and Celdon green as your next...and so on. Not everything gets all the color combos only the darkest areas.
Here is today's progress.
