Color Palette Generator
Transform any color into complete, harmonious color palettes using established color theory principles. Our palette generator creates multiple color variations and combinations that work together perfectly.
Color Harmony Generation
Generate matching colors using seven different harmony rules:
- Complementary Colors: Creates high-contrast combinations using colors from opposite sides of the color wheel
- Analogous Colors: Generates harmonious schemes using colors that sit next to each other on the color wheel
- Triadic Colors: Produces balanced color schemes using three colors equally spaced around the color wheel
- Split Complementary: Offers a softer contrast by using the colors adjacent to the complement
- Square Colors: Creates dynamic four-color schemes using colors spaced evenly around the color wheel
- Tetradic Colors: Generates rich palettes using two complementary color pairs
- Monochromatic Colors: Develops subtle variations using different shades and tints of the same color
Color Variations
Each selected color automatically generates additional variations:
- Five lighter tints for highlighting and backgrounds
- Five darker shades for depth and emphasis
- Automatic adjustment of saturation and brightness
- Preview of all variations in a visual grid
- One-click copying of any variation
