I took my book down to the basement with me this time to remind me of some more ways to lay out the blocks. I think the dominant color here is purple because I see purple pinwheels when I first look at it.
Blocks of color.
Center square with vibrating rounds.
I rotated a few of the corner blocks to get the bands across the corners.
Just like a log cabin barn raising pattern. 
We had severe weather warnings last evening but the storms passed quickly and we got rain and the tornado warnings were south and east of us. Severe storms are the ones that usually produce migraines so I hope I'm lucky this time and don't get one.
