Color Lab

How #EFF5FB 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 47/100
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 3/100
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 6/100
Very low
Playful and accessible rather than exclusive.
Brand distinctiveness 4/100
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.

Very high
Calm enough for large fills — backgrounds, cards, sections.
Print safety 98/100
Very high
Reproduces faithfully in CMYK — safe for packaging and print.
