Light grey vs Tranquil Dawn Color Comparison
Digital color is approximate.

Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Light grey reads slightly lighter here — a subtle but real difference in how open the space feels.
