Color Scheme Generator

Pick a base color and get a full palette, complementary, analogous, triadic, tetradic or monochromatic. Copy any swatch as HEX, RGB or HSL. Nothing leaves your browser.

How Color Scheme Generator works

Color scheme generator takes a single base color and produces a full palette of harmonious colors, complementary, analogous, triadic, tetradic and monochromatic variations. Each generated swatch shows its HEX and RGB values so you can copy them straight into your design or code.

Where Color converter works with one color in multiple formats and Color palette extracts colors from an existing image, Color scheme is the generative starting point: you supply one color and get back a complete design system. Enter the base in HEX, RGB or HSL, and every swatch is shown in all three formats with its values ready to copy.

Frequently asked questions

Is the color value I enter sent anywhere?

No. Harmony calculations, complementary, analogous, triadic, tetradic, monochromatic, are pure mathematics applied locally in your browser. No data is transmitted to Sunasty or any third party.

What is the difference between each harmony type?

Complementary uses one color and its opposite on the color wheel (high contrast). Analogous uses three colors adjacent on the wheel (harmonious, low contrast). Triadic spaces three colors equally at 120°. Tetradic uses four colors at 90° intervals. Monochromatic varies only the lightness of the base color.

Can I start from a HEX code, RGB or HSL value?

Yes. Enter your base color in whichever format you have, HEX, RGB or HSL, and the tool accepts all three. The generated swatches are shown in all formats so you can pick the one your design tool expects.

Does it work offline?

Yes, once the page has loaded. Because the processing happens on your device, you can disconnect from the network and the tool keeps working. This is the clearest proof that your data never leaves your machine.
