Color Lab

How #3FD4DF 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 18/100

Cool

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

Softness 62/100

High

Middle-weight — neither delicate nor heavy.

Depth 20/100

Low

Airy and open — recedes, leaves the composition light.

Naturalness 9/100

Very low

Reads engineered rather than organic — synthetic, digital.

Vintage feel 32/100

Low

A faint retro warmth without tipping into sepia.

Luxury 27/100

Low

Understated — leans refined without going austere.

Brand distinctiveness 47/100

Moderate

Recognisable but shares space with nearby hues.

UI accent fit 28/100

Low

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

Moderate

Usable as a tinted surface in measured doses.

Print safety 68/100

High

Prints close, with a slight loss of vibrancy.
