How #89EFF4 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 25/100

Cool

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

Softness 73/100

High

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

Depth 11/100

Very low

Airy and open — recedes, leaves the composition light.

Naturalness 11/100

Very low

Reads engineered rather than organic — synthetic, digital.

Vintage feel 29/100

Low

A faint retro warmth without tipping into sepia.

Luxury 17/100

Very low

Playful and accessible rather than exclusive.

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

High

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

Print safety 75/100

High

Reproduces faithfully in CMYK — safe for packaging and print.
