Color Lab

How Cool Gray actually behaves in design work — read from its OKLCH lightness, chroma and hue, not just its raw numbers. Ten signals to help you decide where this color earns its place.

Warmth 42/100
Neutral
Balanced temperature — flexible, sits between warm and cool schemes.
Softness 64/100
High
Soft and easy on the eye — gentle backdrops, calm surfaces.
Depth 32/100
Low
Airy and open — recedes, leaves the composition light.
Naturalness 0/100
Very low
Reads engineered rather than organic — synthetic, digital.
Vintage feel 40/100
Low
A faint retro warmth without tipping into sepia.
Luxury 38/100
Low
Understated — leans refined without going austere.
Brand distinctiveness 15/100
Very low
Quiet and neutral — a supporting tone, not a signature.
UI accent fit 48/100
Moderate
Workable accent with care around contrast.
Surface fit 56/100
Moderate
Usable as a tinted surface in measured doses.
Print safety 94/100
Very high
Reproduces faithfully in CMYK — safe for packaging and print.
