Ok, so not these colors, but I LOVE this. This brings a bit of "funkyness" that I think I've been looking for/trying to find the word for. Instead of the primary colors, maybe even just one ocean/green blue tile, or a set of the variety of shade tiles at the top of the wall, and white at the bottom, and pixelated in between. I'm mostly just thinking on the back wall, but if you like the ceiling idea and don't think it'd add too much complication, that could be really cool.
