How #C6C9EA 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 41/100

Neutral

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

Softness 78/100

High

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

Depth 15/100

Very low

Airy and open — recedes, leaves the composition light.

Low

A faint retro warmth without tipping into sepia.

Luxury 21/100

Low

Playful and accessible rather than exclusive.

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

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

Very high

Reproduces faithfully in CMYK — safe for packaging and print.
