I'd play a lot with concentric strip squares layouts, and use the black squares for some show-off quilting in a variegated or multicolor thread, or maybe a simply applique with echo quilting in the variegated/multicolor thread.

I really like those nice bright blocks and looking forward to seeing the finished quilt

You can also think of these blocks as Log Cabin blocks (black is the dark side) and use any log cabin setting

I think you are going to have a great time playing with them & will come up with a gorgeous quilt
WOW - great looking blocks - love the black you added to the blocks - really makes your colors pop.
