Apollo Blue

CW-645

Apollo Blue is a cool, grayed blue with a chalky quality derived from its mix of blue, black, and white pigments. At an LRV of 23.7 it sits in the lower-mid range of reflectance, reading noticeably muted under both daylight and artificial sources. The hue leans slightly toward blue-green on the wall, though the gray component keeps it from appearing saturated.

Silver Satin and Gray Owl work as lighter neighboring tones on trim or upper walls, while Alexandria Beige introduces a warm offset. For a clean ceiling or wainscot pairing, Simply White maintains contrast without competing with the blue cast.

Apollo Blue 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.
