How to Generate Color Palettes

Problem

You have a brand color and need a full palette of harmonious colors for a design system.

Prerequisites

• Understanding of color theory
• Knowledge of color harmonies

Steps

1. 1. Choose a base color and harmony type

   Select your base color (e.g., brand blue #0066CC). Choose a harmony scheme: complementary (opposite on the wheel), analogous (adjacent), triadic (evenly spaced), or split-complementary. The harmony type determines the relationship between palette colors.

   Input

   base: #0066CC, harmony: analogous

   Output

   scheme selected

2. 2. Generate the palette

   Convert the base color to HSL, then rotate the hue to generate harmony colors. For analogous, use ±30° hue shifts. For complementary, use 180°. For triadic, use 120° and 240°. Generate shades and tints by adjusting lightness for a full range.

   Input

   base + analogous

   Output

   #0066CC, #003DCC, #0099CC, ...

3. 3. Refine and organize

   Review the generated palette for visual harmony and accessibility. Add neutral colors (grays) for text and backgrounds. Ensure sufficient contrast between palette colors. Organize into a design system with primary, secondary, accent, and neutral roles.

   Input

   raw palette

   Output

   structured design system

Expected result

A harmonious color palette with sufficient variety and contrast for a design system.

Common errors

Palette colors clash

Try a different harmony type. Analogous is safest; complementary can be jarring. Adjust saturation and lightness to harmonize.

Insufficient contrast for text

Check contrast ratios between palette colors. Ensure at least one combination meets WCAG 4.5:1 for text.

Troubleshooting

• If the palette feels off, adjust the base color's saturation or try a different harmony.
• Test the palette in context (buttons, text, backgrounds) before finalizing.

Security limits

• Color palette generation is a design tool with no security implications.
