How it works
Generate your palette in three steps
Enter or pick a base color
Input a HEX or RGB value, or use the integrated color picker to choose your starting color. This becomes the seed color for generating the full palette.
Select a harmony scheme
Choose from complementary, analogous, triadic, tetradic, split-complementary, or monochromatic. The tool applies color wheel geometry to derive each color in the set.
Export your palette
Copy individual HEX codes with one click, or export the full palette as a CSS custom properties block or a comma-separated HEX list, ready to paste directly into your project.
FAQ
Common questions about color palettes
What is a color harmony scheme?
Color harmony schemes are relationships between colors based on their positions on the color wheel, chosen because they tend to produce visually coherent combinations. Common schemes include: complementary (two colors directly opposite each other), analogous (three to five adjacent colors), triadic (three colors spaced 120u00b0 apart), tetradic or square (four colors at 90u00b0 intervals), split-complementary (a color plus the two flanking its opposite), and monochromatic (variations in lightness and saturation of a single hue). Each scheme creates a different visual character and level of contrast.
Which scheme should I use for a website or app?
For most digital interfaces, analogous or monochromatic schemes produce a cohesive, easy-to-navigate visual experience because the colors feel related without competing. Complementary schemes create strong contrast and are effective for call-to-action elements when used sparingly as an accent. Triadic and tetradic schemes are vibrant and dynamic but require careful management of saturation to avoid visual overload. A common practical approach is to use a monochromatic or analogous palette for backgrounds and neutral surfaces, then introduce a complementary or triadic accent for interactive elements.
How do I use this palette in my CSS?
Once you have your palette, assign the HEX codes to CSS custom properties in your root stylesheet. For example: –color-primary: #3a86ff; –color-accent: #ff006e;. Using custom properties makes it straightforward to apply and update colors throughout your entire project from a single location. This tool’s export button formats your palette directly as a CSS :root { } variable block with descriptive variable names, ready to paste without any reformatting.
Does color palette generation replace a professional designer?
For many projects u2014 particularly personal tools, early-stage products, or utility interfaces u2014 a harmony-based palette generator is a practical and effective starting point. However, professional color design involves more than mathematical harmony: it also considers brand personality, cultural associations, typographic pairing, and real-world lighting conditions. Generated palettes should be validated for sufficient contrast ratios using a separate contrast checker and reviewed in context before being finalised for production use.
