The best paint color for a bathroom
The color I recommend most for bathroom walls is without question, pink. Not a bright pink but a soft, muted pink. The main reason for that is, it is pretty universally flattering to every skin tone so you will look and feel good in a pink bathroom. It is feminine while also feeling moody, and pairs really well with more masculine finishes like dark wood and stone.
Some of my favorite pink paint colors:
White Truffle by Sherwin Williams
Ointment Pink by Farrow & Ball
Setting Plaster by Farrow & Ball
Other favorite ideas for using pink:
Pink Flamingo marble
Pink zellige tiles
Accent lighting with a pink glass shade
