Color Lab

How #EFFAFF 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 46/100

Neutral

Balanced temperature — flexible, sits between warm and cool schemes.

Softness 95/100

Very high

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

Depth 2/100

Very low

Airy and open — recedes, leaves the composition light.

Naturalness 0/100

Very low

Reads engineered rather than organic — synthetic, digital.

Vintage feel 13/100

Very low

Clean and current — no dusty, aged cast.

Luxury 4/100

Very low

Playful and accessible rather than exclusive.

Brand distinctiveness 5/100

Very low

Quiet and neutral — a supporting tone, not a signature.

UI accent fit 2/100

Very low

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

Surface fit 94/100

Very high

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

Print safety 96/100

Very high

Reproduces faithfully in CMYK — safe for packaging and print.
