How #6DE2EF 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 21/100

Cool

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

Softness 68/100

High

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

Depth 15/100

Very low

Airy and open — recedes, leaves the composition light.

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