Lighting Behavior
Stays white in every lighting condition. The benchmark white that other whites are compared against.
Every paint color looks different depending on the light source in your room. South-facing rooms get warm, direct sunlight that brings out yellow and warm undertones. North-facing rooms get cool, indirect light that emphasizes blue and gray undertones. East-facing rooms are bright and warm in the morning, cooler in the afternoon. West-facing rooms are the opposite: cool morning, warm afternoon. Incandescent and warm LED bulbs push colors warmer, while cool-white LEDs and fluorescent tubes push colors cooler. To avoid surprises, always test Ultra Pure White with a physical sample on your actual wall, and observe it at different times of day before committing.
