My 2 walls facing echother is painted red already . I have a huge window (balcony light) coming from the oposite side of the red wall. Now the side 2 other walls I want to paint darker grey and I'm not sure if it will match. Should I just leave it white? It's not really red its like the tip of a match color . Or even the juice of cherry . The name of the color is haunting melody . It looks amazing (the picture is not fully painted
