Cool Colors
Colors in the blue-green-violet range of the color wheel — perceived as calm, professional, and visually receding.
What it means
Cool colors roughly span hues from 150° to 270° on the color wheel: greens, cyans, blues, and violets. They're associated with water, sky, ice, and shadow.
Cool colors appear to recede — they seem farther from the viewer than warm colors, creating a sense of spaciousness and depth. This makes them ideal for backgrounds and large surfaces where you want the content, not the surface, to command attention.
Why it matters in palette design
Cool-dominant palettes feel professional, trustworthy, and expansive. Finance apps, enterprise tools, and healthcare products frequently use cool palettes because they convey reliability without emotional intensity. In PerfectPalette, a cool-dominant palette with a single warm accent creates the strongest possible visual hierarchy — the warm element jumps forward against the cool foundation.
Example
A banking app uses deep blue (#1E3A5F) for its primary and slate gray for surfaces. The entire interface feels cool, calm, and trustworthy. The one warm element — an amber alert banner for security notifications — commands immediate attention precisely because it breaks the temperature pattern.
