A classic blue bathroom color, reminiscent of the sky and water. Blue calms and relaxes; blue also inspires confidence and trust. A traditional shade for bathrooms, blue can be used as an accent with many other colors, or as the main one.
On the color wheel, blue moves from purple to aqua, giving you a wide range of possibilities. Pale blue expands space and has a calming, airy effect; dark blue feels masculine, strong, and cozy. Add bright yellow accents for a tropical aquarium effect, or use green for a more organic, flower-like style.
