Color Lab

How #ADD5DA 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 38/100

Neutral

Balanced temperature — flexible, sits between warm and cool schemes.

Softness 79/100

High

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

Depth 15/100

Very low

Airy and open — recedes, leaves the composition light.

Naturalness 4/100

Very low

Reads engineered rather than organic — synthetic, digital.

Vintage feel 26/100

Low

A faint retro warmth without tipping into sepia.

Luxury 20/100

Low

Playful and accessible rather than exclusive.

Brand distinctiveness 16/100

Very low

Quiet and neutral — a supporting tone, not a signature.

UI accent fit 12/100

Very low

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

Surface fit 72/100

High

Calm enough for large fills — backgrounds, cards, sections.

Print safety 89/100

Very high

Reproduces faithfully in CMYK — safe for packaging and print.
