Color Palette Generator

A smart color palette generator for UI/UX designers and web developers. Select a base color and instantly generate mathematically harmonious palettes including monochrome, complementary, analogous, and triadic schemes. Export your palettes instantly to HEX codes, CSS Variables, or JSON formats for seamless workflow integration.

 

What is the Color Palette Generator?

The Color Palette Generator takes a single base color and uses color math (HSL space) to calculate perfectly harmonious color schemes. It removes the guesswork from UI design by providing mathematically sound palettes.

How to Use

  1. Pick a base color using the color picker or HEX input.
  2. Select a palette generation rule (e.g., Analogous, Triadic, Monochrome).
  3. The tool instantly generates a 5-color palette based on your base color.
  4. Click "Generate Random" to get inspired with a completely random palette.
  5. Choose your preferred export format (HEX list, CSS Variables, or JSON).
  6. Click the Copy button to grab the code.

Common Use Cases

  • Creating a cohesive theme for a new website or web application.
  • Finding an accent color that complements an existing brand logo.
  • Generating a structured JSON color dictionary for a Tailwind config or design system.

Key Benefits

  • Instant generation using client-side color math.
  • Guaranteed visual harmony through standard color theory rules.
  • Multiple developer-friendly export formats save time.
  • 100% free and private.

Frequently Asked Questions

What is a complementary color scheme?

A complementary color scheme uses colors that are opposite each other on the color wheel. This creates a high contrast, vibrant look that is great for highlighting important UI elements like buttons.

What is an analogous color scheme?

Analogous color schemes use colors that are next to each other on the color wheel. They usually match well and create serene and comfortable designs, often found in nature.

How do I use the CSS Variables export?

Select the "CSS Vars" export option, click copy, and paste the code into your stylesheet (usually inside a :root {} selector). You can then use those variables throughout your CSS like background-color: var(--color-primary);.

What is a monochrome color scheme?

A monochrome (or monochromatic) scheme takes a single base color and creates a palette by altering only its lightness and saturation. This guarantees the colors will match perfectly and creates a very clean, unified look.

What is a triadic color scheme?

A triadic scheme uses three colors that are evenly spaced around the color wheel (forming a triangle). It provides high contrast while maintaining better visual harmony than a strict complementary scheme.

How does the color math work?

The tool converts your HEX or RGB base color into the HSL (Hue, Saturation, Lightness) color space. It then mathematically rotates the Hue degree (e.g., +180 for complementary) to find the mathematically perfect matching colors.

Why generate a JSON color palette?

JSON is the standard data format for configuring modern styling frameworks like Tailwind CSS, Material-UI, or styled-components. Exporting to JSON allows you to paste the palette directly into your config files.

Can I generate a random palette?

Yes! If you are stuck for inspiration, click the "Generate Random" button. The tool will pick a random base color and instantly apply the selected generation rule.

What happens if I change the lightness?

Changing the lightness allows you to create pastel palettes (higher lightness) or deep, dark palettes (lower lightness) without changing the fundamental color harmony.

Is this tool free for commercial use?

Absolutely. Any color palette you generate using this tool is completely free to use for both personal and commercial projects without attribution.
