Benjamin Moore

O'Reilly Green

555

O'Reilly Green by Benjamin Moore is a light green with a noticeable yellow undertone that gives it a slightly luminous quality. With an LRV of 74.12, it reflects a substantial amount of light and can make spaces appear larger and more open, functioning well in kitchens, sunrooms, and bathrooms. Its hue stays in the yellow-green range without reading overtly chartreuse.

The shade works alongside White Dove and Swiss Coffee for a neutral backdrop, while Palladian Blue, Windham Cream, and Hale Navy extend the palette into cooler or deeper territory.

O'Reilly Green 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.
