I'd take the four on the left shopping with me and look for a brighter focus fabric or other coordinating fabrics. Those four are all toned (grayed), but you wouldn't have to stick to toned fabrics for the rest of the group. A green and pink fabric would add some punch. Even a toned green (the complimentary color) would be a welcome addition.
I'd put the three on the right back into my stash to use for neutrals in another project. One always needs neutrals!
