How #91CBE0 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 30/100

Cool

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

Softness 72/100

High

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

Depth 18/100

Very low

Airy and open — recedes, leaves the composition light.

Very low

Low

A faint retro warmth without tipping into sepia.

Luxury 25/100

Low

Understated — leans refined without going austere.

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

High

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

Very high

Reproduces faithfully in CMYK — safe for packaging and print.
