Color Lab

How #7EECDF 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 28/100
Cool
Reads cool and recessive — calming, technical, good for trust-led UI.
Softness 70/100
High
Soft and easy on the eye — gentle backdrops, calm surfaces.
Depth 13/100
Very low
Airy and open — recedes, leaves the composition light.
Naturalness 28/100
Low
Loosely natural — an earthy edge without being rustic.
Vintage feel 31/100
Low
A faint retro warmth without tipping into sepia.
Luxury 19/100
Very low
Playful and accessible rather than exclusive.
Brand distinctiveness 40/100
Moderate
Recognisable but shares space with nearby hues.
UI accent fit 12/100
Very low
Weak as an action color — too pale, too dark or too muted to signal.
Surface fit 57/100
Moderate
Usable as a tinted surface in measured doses.
Print safety 76/100
High
Reproduces faithfully in CMYK — safe for packaging and print.
