How #C4F5FD 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 85/100

Very high

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

Depth 6/100

Very low

Airy and open — recedes, leaves the composition light.

Low

High

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

Very high

Reproduces faithfully in CMYK — safe for packaging and print.
