Color Lab

How #9FEED9 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 36/100
Cool
Reads cool and recessive — calming, technical, good for trust-led UI.
Softness 75/100
High
Soft and easy on the eye — gentle backdrops, calm surfaces.
Depth 11/100
Very low
Airy and open — recedes, leaves the composition light.
Naturalness 42/100
Moderate
Loosely natural — an earthy edge without being rustic.
Vintage feel 32/100
Low
A faint retro warmth without tipping into sepia.
Luxury 16/100
Very low
Playful and accessible rather than exclusive.
Brand distinctiveness 32/100
Low
Recognisable but shares space with nearby hues.
UI accent fit 9/100
Very low
Weak as an action color — too pale, too dark or too muted to signal.
Surface fit 64/100
High
Calm enough for large fills — backgrounds, cards, sections.
Print safety 83/100
Very high
Reproduces faithfully in CMYK — safe for packaging and print.
