Color Lab

How #5EE3EF 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 19/100

Cool

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

Softness 66/100

High

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

Depth 15/100

Very low

Airy and open — recedes, leaves the composition light.

Naturalness 9/100

Very low

Reads engineered rather than organic — synthetic, digital.

Vintage feel 29/100

Low

A faint retro warmth without tipping into sepia.

Luxury 22/100

Low

Playful and accessible rather than exclusive.

Brand distinctiveness 45/100

Moderate

Recognisable but shares space with nearby hues.

UI accent fit 17/100

Very low

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

Surface fit 50/100

Moderate

Usable as a tinted surface in measured doses.

Print safety 69/100

High

Prints close, with a slight loss of vibrancy.
