Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Coastal Grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Digital color is approximate.

Before committing to either color, test physical samples in your own space under the light you actually live with.
