Benjamin Moore

Oystershell

864 / HC-171

Oystershell by Benjamin Moore is a soft blue-gray with balanced cool undertones that keep it from leaning too strongly toward blue or neutral gray. Its light reflectance value of 67.87 places it in the upper-mid brightness range, providing enough reflectance to maintain an open feel while delivering visible color on walls. The hue reads as a quiet, muted tone that works in bedrooms, living rooms, and bathrooms where a restrained cool palette is appropriate.

It adapts to both contemporary and traditional settings. Oystershell pairs naturally with Benjamin Moore's Chantilly Lace, Gray Owl, Kendall Charcoal, Blue Bonnet, and Stonington Gray.
