Color Lab

How #4EDDEA 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 18/100

Cool

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

Softness 64/100

High

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

Depth 17/100

Very low

Airy and open — recedes, leaves the composition light.

Naturalness 8/100

Very low

Reads engineered rather than organic — synthetic, digital.

Vintage feel 30/100

Low

A faint retro warmth without tipping into sepia.

Luxury 24/100

Low

Playful and accessible rather than exclusive.

Brand distinctiveness 47/100

Recognisable but shares space with nearby hues.

UI accent fit 21/100

Low

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

Moderate

Usable as a tinted surface in measured doses.

Print safety 68/100

High

Prints close, with a slight loss of vibrancy.
