Color Lab

How #89E6DD 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 13/100
Very low
Airy and open — recedes, leaves the composition light.
Naturalness 24/100
Low
Reads engineered rather than organic — synthetic, digital.
Vintage feel 34/100
Low
A faint retro warmth without tipping into sepia.
Luxury 20/100
Very low
Playful and accessible rather than exclusive.
Brand distinctiveness 35/100
Low
Recognisable but shares space with nearby hues.
UI accent fit 13/100
Very low
Weak as an action color — too pale, too dark or too muted to signal.
Surface fit 60/100
Moderate
Usable as a tinted surface in measured doses.
Print safety 79/100
High
Reproduces faithfully in CMYK — safe for packaging and print.
