Lighting Behavior

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.
