Jane Quilter, I checked your photos in black and white. I would take away the first aqua (too light), and counting from the right, the third, fourth and fifth from the right read as dark as your browns, so I would be mindful of using them next to the brown. I think your first photo of corals is good, and in the second coral photo, the first could be moved to neutrals and the fifth removed, as the background is very light. I think the first, second and bottom fabric in your peachy neutrals photo could serve as neutrals. Your fabrics are beautiful!
