Warmth 34/100

Cool

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

Softness 72/100

High

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

Very low

Airy and open — recedes, leaves the composition light.

Understated — leans refined without going austere.

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

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

Reproduces faithfully in CMYK — safe for packaging and print.
