How #91C4BC 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 39/100

Neutral

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

Airy and open — recedes, leaves the composition light.

Understated — leans refined without going austere.

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

Reproduces faithfully in CMYK — safe for packaging and print.
