Warmth 13/100
Cool
Reads cool and recessive — calming, technical, good for trust-led UI.
Softness 48/100
Moderate
Middle-weight — neither delicate nor heavy.
Depth 39/100
Low
Mid depth — usable as an accent or a muted ground.
Naturalness 0/100
Very low
Reads engineered rather than organic — synthetic, digital.
Vintage feel 44/100
Moderate
A faint retro warmth without tipping into sepia.
Luxury 46/100
Moderate
Understated — leans refined without going austere.

Recognisable but shares space with nearby hues.
UI accent fit 88/100
Very high
Strong interactive accent — visible and can carry a legible label.
Surface fit 25/100
