Why is it called Cyan?

Cyan comes from the Greek "kyanos", meaning a dark blue substance. Today it names the pure blue-green primary of the printed and on-screen colour models.

Color Lab

How Cyan 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 12/100

Cool

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

Softness 63/100

High

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

Depth 10/100

Very low

Airy and open — recedes, leaves the composition light.

Naturalness 12/100

Very low

Reads engineered rather than organic — synthetic, digital.

Vintage feel 19/100

Very low

Clean and current — no dusty, aged cast.

Luxury 14/100

Very low

Playful and accessible rather than exclusive.

Brand distinctiveness 60/100

Moderate

Recognisable but shares space with nearby hues.

UI accent fit 9/100

Very low

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

Surface fit 46/100

Moderate

Usable as a tinted surface in measured doses.

Print safety 61/100

High

Prints close, with a slight loss of vibrancy.
