–I have no idea how a darker color on white would look. Try a small area first 🙂
I have seen darker on top of white- in my case, fire engine red on top of white…it was in a little boy’s room. Personally, I didn’t care for it..but Red in large quanity is too much for me. The look was almost like the blue spattered tin cook ware from years and years ago…very stark contrast. You may like that look, and if so, that’s wonderful- this is jmho, ok?
