Keystone Gray

HDC-AC-21

Keystone Gray is a light warm gray with a faint green-beige cast. It reads as a soft neutral. The shade can work across hallways, living areas, or bedrooms when a cool gray would feel too sharp.

Warm floors make it more beige. White trim gives it cleaner definition. It is not dramatic. Sample beside stone and upholstery, because low-saturation grays take direction from nearby materials.

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.
