Frequently Asked Questions

How does the generator create harmonious palettes from a single HEX color?

The engine converts your base HEX color into the HSL (Hue, Saturation, Lightness) cylindrical color space. By rotating the Hue angle around the 360-degree color wheel and modulating Lightness and Saturation, it calculates mathematically balanced 5-swatch harmonies.

What is the difference between Monochromatic, Analogous, Complementary, and Triadic palettes?

Monochromatic palettes keep a single hue and vary lightness/saturation for clean UI hierarchy. Analogous palettes use adjacent hues (±30°) for calm, cohesive designs. Complementary palettes pair opposite hues (180° apart) for high-impact contrast, and Triadic palettes space hues 120° apart for vibrant balance.

How does selecting a Harmony Mode affect the generated CSS and copied output?

Selecting Monochromatic, Analogous, Complementary, or Triadic sets that harmony as the active primary scheme—updating both the one-click copyable HEX list and the '--color-selected-1' through '--color-selected-5' CSS custom properties while still displaying all four harmonies for comparison.

Can I input 3-digit shorthand HEX colors like #F0A?

Yes. The color engine accepts both 3-digit shorthand HEX codes (like #F0A, automatically expanded to #FF00AA) and standard 6-digit HEX codes, ensuring accurate RGB-to-HSL conversion without fallback errors.

How should I apply a 5-color palette to a web UI using the 60-30-10 rule?

Allocate 60% of the viewport to neutral or light monochromatic tints (backgrounds and cards), 30% to your base or analogous brand hue (headers, sidebars, secondary surfaces), and 10% to a high-contrast complementary or triadic accent color for primary call-to-action buttons.
