Color Lab

How #3ACFFC 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 10/100

Cool

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

Softness 59/100

Moderate

Middle-weight — neither delicate nor heavy.

Depth 21/100

Low

Airy and open — recedes, leaves the composition light.

Naturalness 1/100

Very low

Reads engineered rather than organic — synthetic, digital.

Vintage feel 28/100

Low

A faint retro warmth without tipping into sepia.

Low

Understated — leans refined without going austere.

Brand distinctiveness 52/100

Moderate

Recognisable but shares space with nearby hues.

UI accent fit 29/100

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

Low

Usable as a tinted surface in measured doses.

High

Prints close, with a slight loss of vibrancy.
