I concur with the post that the colors all work but maybe less in each block? a few colors a few blenders? Also if you imagine the block with the dots on the top (triangles?) if those had been a solid or mottled light color in each one it would make the patterns below pop out. I saw it and first thing I thought was darn if those had been one of the light colors in your blocks then the whole thing would have changed up a ton.
