How #277EEA 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 5/100

Cool

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

Softness 40/100

Low

Middle-weight — neither delicate nor heavy.

Depth 42/100

Moderate

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

Naturalness 0/100

Very low

Reads engineered rather than organic — synthetic, digital.

Vintage feel 28/100

Low

A faint retro warmth without tipping into sepia.

Luxury 44/100

Moderate

Understated — leans refined without going austere.

Brand distinctiveness 49/100

Moderate

Recognisable but shares space with nearby hues.

UI accent fit 85/100

Very high

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

Surface fit 17/100

Very low

Too saturated or mid-toned for big areas — keep it to accents.

Print safety 63/100

High

Prints close, with a slight loss of vibrancy.
