We have a thread dedicated to scrappy quilts to give you some inspiration:

I like a bit of control, either a specific color way, or grab & sew, but a single unifying fabric repeated in each block, or sashed with a single fabric.
As mentioned, a design wall is very helpful for color distribution and/or possibly discarding those one or two blocks that you think are just too much!
