Need help with colors for Home Gym. we have a small area that we are making into a home gym. there are exposed ceilings that we thought about painting a flat black or even Wrought Iron from Benjamin Moore. The flooring will be the black rubber gym flooring. I was thinking of maybe painting the walls a revere Pewter? Would this be too dark with ceilings and floors being dark in colors. I don't want that closed-in feeling but we don't want to finish the ceiling fear of lowering them more. The rubber flooring also has blue specks in it which not really sure how much that really matters. Any advice would be helpful
