Understanding Color Harmony

What is Color Harmony?

Color harmony is the theory of combining colors in a way that is visually pleasing. It's based on the color wheel and how colors relate to each other. Good harmony creates balance and order in design.

Why Does It Matter?

Harmonious colors create a more professional, cohesive look. They guide the viewer's eye, evoke emotions, and improve readability. Poor color choices can make designs feel chaotic or unprofessional.

When to Use Color Harmony Checker

🎨 Testing Color Combinations

Before finalizing any color scheme, test it against the six harmony rules: complementary, analogous, triadic, tetradic, split-complementary, and square. Ensure your colors work together.

📱 UI Color Validation

Check if your UI color palette follows established harmony principles. A harmonious palette feels cohesive and professional — disharmonious colors create visual tension.

🎯 Brand Palette Refinement

Fine-tune your brand colors by testing different harmony relationships. Find the perfect secondary and accent colors that harmonize with your primary brand color.
