What Harmony Engine shows
Palette Harmony Engine analyzes how the colors relate to each other. It gives you a harmony score, a harmony family, a suggested use case, and a temperature reading. These values help you understand why a palette feels calm, energetic, premium, playful, technical, or mixed.
Harmony score
The harmony score is a quick quality signal for how consistently the colors work together. A higher score usually means the palette has a clearer relationship between hues, saturation, and brightness. A lower score does not always mean the palette is bad, but it usually means it needs more care when used in a real interface.
Harmony type
The harmony type describes the palette structure. Monochromatic palettes stay close to one hue. Analogous palettes use neighboring hues. Complementary palettes use opposite colors. Triadic, tetradic, square, and split complementary palettes create stronger contrast and more energy. Achromatic palettes are based around neutral colors, while mixed palettes are less tied to one strict color relationship.
Best-for label
The best-for label suggests where the palette naturally fits. For example, a restrained and reliable palette may fit fintech or corporate products, while a warm and expressive palette may fit branding, editorial work, wellness, or playful interfaces. Treat it as guidance, not a rule.
Temperature
Temperature tells you whether the palette reads as warm, cool, balanced, or neutral. Warm palettes often feel energetic, friendly, or emotional. Cool palettes often feel calm, technical, or professional. Balanced palettes mix both sides, while neutral palettes rely more on grayscale or low-saturation colors.
How to use the result
Use Harmony Engine before committing to a palette. If the harmony type and best-for label match the project, the palette is a stronger candidate. If they do not match, you can still use the palette, but you should be more careful with role assignment, contrast, and brand tone.
