How it works
A useful palette is a system of relationships, not just a handful of unrelated colors. This generator starts with your chosen seed and transforms its hue, saturation, or lightness according to the selected method. Hue rotations produce relationships such as complementary, analogous, and triadic schemes. Lightness changes create tints and shades, while controlled interpolation creates smooth scales and gradients. Every calculation happens locally in JavaScript, and the resulting values are formatted for direct use in CSS or a design system. Generated colors are a strong starting point, but context still matters: check text contrast, test the palette on real interface elements, and adjust emphasis for your product. The preview is surrounded by a neutral surface so the colors are easier to judge without a strongly colored page background shifting your perception.
Frequently asked questions
What can I use the CSS Gradient Generator for?
Use it for quick design decisions, CSS work, prototypes, and checking values without opening a full design application.
How accurate are the results?
The calculations use standard deterministic color formulas. Small rounding differences are normal, and print results always depend on the printer and color profile.
Can I copy the results?
Yes. Use the copy controls beside values or copy the generated code block directly.
Is my color or image uploaded or stored?
No. This tool runs entirely in your browser. Your values and images are processed on your device and are never uploaded, stored, or sent to an API.
Does it work on mobile?
Yes. The interface is responsive and the core calculations work in modern mobile browsers. A few native features, such as EyeDropper, depend on browser support.
