Color Lab

How #90CDC0 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 38/100

Cool

Reads cool and recessive — calming, technical, good for trust-led UI.

Softness 71/100

High

Soft and easy on the eye — gentle backdrops, calm surfaces.

Depth 19/100

Very low

Airy and open — recedes, leaves the composition light.

Naturalness 29/100

Low

Loosely natural — an earthy edge without being rustic.

Vintage feel 36/100

Low

A faint retro warmth without tipping into sepia.

Luxury 26/100

Low

Understated — leans refined without going austere.

Brand distinctiveness 25/100

Quiet and neutral — a supporting tone, not a signature.

UI accent fit 22/100

Weak as an action color — too pale, too dark or too muted to signal.

Surface fit 61/100

High

Calm enough for large fills — backgrounds, cards, sections.

Print safety 86/100

Very high

Reproduces faithfully in CMYK — safe for packaging and print.
