Warmth 26/100

Cool

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

Softness 71/100

High

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

Depth 15/100

Very low

Airy and open — recedes, leaves the composition light.

Very low

Reads engineered rather than organic — synthetic, digital.

Vintage feel 33/100

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.

Moderate

Usable as a tinted surface in measured doses.

Reproduces faithfully in CMYK — safe for packaging and print.
