Lee in Richmond

I fell for these bright yellow/touch of orange fabrics yesterday, and then found a few more in my stash. I do not know whether these might be too much the same to work in a scrap quilt? I tried out a few solids for maybe small keystones. . .the green isn't as gaudy as it looks -- maybe a green should be more of an apple? Could the blue work? a deep cinnamon?

I am thinking maybe 'stacked coins', or just a jelly roll. . . I have trouble visualizing whether these would just blend into a near-solid. What do you think? Any ideas for a pattern appreciated!
