Warmth 9/100

Cool

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

Softness 35/100

Low

Middle-weight — neither delicate nor heavy.

Depth 52/100

Moderate

Mid depth — usable as an accent or a muted ground.

Naturalness 0/100

Very low

Reads engineered rather than organic — synthetic, digital.

Strong interactive accent — visible and can carry a legible label.

Surface fit 9/100
