Valspar

Blue Coal

4011-3

Blue Coal is nearly black, with a navy cast that shows only when light hits it. Reserve it for spots that can handle an inky navy shadow. It suits a front door, library built-ins, or a small accent wall where the finish can look dense and tailored.

LRV 3 means it will swallow weak light. Satin or semigloss helps the color avoid a flat, chalky appearance on trim and cabinets.

Blue Coal in Different Light

Light temperature is measured in Kelvin: a warm 2700K bulb pulls colors toward yellow, while 5000K daylight reads cooler and truer. Check the color at the time of day you actually use the room.

LRV measures how much light a color reflects, from 0 (black) to 100 (pure white). Below about 50 a color needs good lighting to avoid going flat, 60 and up helps brighten a room, and most whites sit above 80.
