The Color Palette Generator creates harmonious color palettes from any base color you choose. Select a color using the picker or enter a hex value, then generate complementary, analogous, triadic, split-complementary, and monochromatic color schemes — complete with hex, RGB, and HSL values ready to use in your CSS, design tools, or style guide.
Step-by-Step
Choose a base color — Use the color picker to select a starting color, or enter a hex code (e.g., #3B82F6) directly.
Select a harmony type — Choose from Complementary, Analogous, Triadic, Split-Complementary, Tetradic, or Monochromatic color schemes.
Adjust parameters — Fine-tune the palette by adjusting hue angle spread, saturation variation, and lightness steps.
Preview the palette — See all generated colors displayed as swatches with their hex, RGB, and HSL values.
Export — Copy individual color values, copy the entire palette as CSS custom properties, or export as a Tailwind CSS color config.
Features
Color Harmony Algorithms — Generate palettes based on proven color theory: complementary (180°), analogous (30°), triadic (120°), split-complementary (150°/210°), and tetradic (90°).
Monochromatic Scales — Create tint and shade scales from your base color with configurable steps (50 through 950, Tailwind-style).
Multiple Formats — Every color is shown in HEX, RGB, HSL, and OKLCH formats. Copy any format with a single click.
Contrast Checking — Each color swatch shows its WCAG contrast ratio against white and black backgrounds, helping you choose accessible text colors.
CSS Custom Properties Export — Export the entire palette as CSS custom properties (--color-primary-500: #3B82F6;) ready for your stylesheet.
Tailwind Config Export — Generate a Tailwind CSS color configuration object with proper shade naming conventions.
Common Use Cases
Brand Identity — Build a complete brand color palette from a single primary color, ensuring all accent and neutral colors are harmonious.
Web Design — Generate primary, secondary, and accent colors for a website design with guaranteed visual harmony.
Design Systems — Create systematic color scales (50–950) for component libraries and design tokens.
Accessibility — Use the built-in contrast checker to ensure your color choices meet WCAG AA or AAA contrast requirements.
Presentations — Quickly generate matching color schemes for slide decks, charts, and data visualizations.
Why Use This Tool
Choosing colors that work well together is one of the hardest parts of design. Color theory provides mathematical relationships between harmonious colors, but applying those calculations by hand is tedious. This generator automates the process and gives you production-ready color values with accessibility information. Whether you're starting a new brand, building a design system, or just need a quick palette for a side project, this tool saves hours of experimentation.
