If you had a two toned nursery...top pink, bottom brown, white wood work and furniture would you go with white letters for babies names? Or another color?
I'd go with white. It will show up well and be complementary with the white woodwork and furniture. As a second choice, I'd go with PP and do the opposite color (e.g. pink on brown).
