Color Palette Generator — Build and Export Color Schemes

Press the space bar or tap the Generate button and a new palette appears instantly. Lock any swatches you want to keep, then keep shuffling — only the unlocked colors change. You can also switch the harmony mode (random, monochrome, analogous, complementary, or triadic) to control how the colors relate to each other on the color wheel.

Yes. Every swatch has a lock button. Locked colors never change when you shuffle, and in harmony modes the first locked color becomes the anchor for the whole scheme — so you can lock your brand color and generate matching monochrome, analogous, complementary, or triadic companions around it.

Your palette is saved into the page URL as you work, in the form ?colors=aabbcc-ddeeff-... Copy the link from the address bar and send it to a teammate or client — opening the link restores the exact same palette, which they can then tweak, reshuffle, or export themselves.

Anywhere from 3 to 8 colors. Five is the default because it maps neatly onto most design systems: a primary, a secondary, an accent, a background, and a text color. When you increase the count, your existing colors are preserved and only the new slots are generated.

Yes. The CSS export produces a ready-to-paste :root block with --color-1 through --color-n custom properties. The JSON export includes hex, RGB, and HSL values for every swatch, and the PNG export renders a labeled color strip you can drop into mood boards, briefs, or slides.

It is free to use and export without creating an account. Palette generation and harmony math stay in your browser.

Almost always one of three things. The file is over the 20 MB free upload limit — Premium takes 50 MB and Pro 120 MB. The format is not one this tool accepts, so check the list shown on the upload panel. Or the file is not really the format its name says: renaming a file does not change what is inside it, and that is the reason a valid-looking file gets refused.

Yes — where there is a strength or intensity control, the default is deliberately obvious so you can see what the tool does. Most photos read better well below it. Bring the strength down until the effect looks like a decision rather than a filter, and compare against your original before you download.

Color Palette Generator supports free standard use within the published processing allowances. Free downloads are clean — no watermark. No signup is required for standard tool use. Photo effects and AI edits have a web-size limit on Free, with the original-resolution result available through Premium or one credit. Crop, resize, rotate, compress and convert stay full size. Published processing allowances and file limits still apply.

No — Color Palette Generator runs in the browser on desktop and phone. There is nothing to install, no trial to start, and no license to buy before you can see whether it does what you need. Try it on the file you are actually stuck with rather than a sample.
