// Generate random colors with preview swatches for design and testing
Use this random color generator for palette ideas, ui testing, chart colors. Use it for palette exploration, chart placeholders, UI swatches, CSS tests, and visual QA where you need quick color variety. Results are generated in the browser, so pasted input stays on the page and can be copied without a server round trip.
Local Generation
Generate multiple swatches for comparison. Useful for palette ideas. Output is local, seedable, and formatted for fast copying into notes, CSV files, forms, or prototypes.
Seeded Results
Check contrast before using text colors. Useful for ui testing. Output is local, seedable, and formatted for fast copying into notes, CSV files, forms, or prototypes.
Copy-Ready Output
Seed a palette for repeatable examples. Useful for chart colors. Output is local, seedable, and formatted for fast copying into notes, CSV files, forms, or prototypes.
// ABOUT THE RANDOM COLOR GENERATOR
How It Works:
Colors are generated from independent red, green, and blue channels, then formatted as HEX, RGB, or an HSL companion value depending on the selected mode.
Example:
this generator + count=10 + optional seed -> copy-ready output
Common Use Cases:
- >Palette ideas
- >UI testing
- >Chart colors
- >Design placeholders
// PRACTICAL GUIDE
Use it for palette exploration, chart placeholders, UI swatches, CSS tests, and visual QA where you need quick color variety.
The preview grid helps catch colors that are too close, too dark, or visually awkward before you copy values into a design or stylesheet.

- >Generate multiple swatches for comparison
- >Check contrast before using text colors
- >Seed a palette for repeatable examples
- >Copy HEX for CSS and design tokens

>> frequently asked questions
Q: Is this generator private?
A: Yes. Generation runs client-side after the page loads. Pasted input, seeds, and values are not submitted by this tool.
Q: How does seeded mode help with palette ideas?
A: A seed makes the same settings return the same sequence again. That helps when you need to replay palette ideas, compare results, or keep a demo fixture stable.
Q: What should I check before using generated values?
A: Generate multiple swatches for comparison. Check contrast before using text colors. Review the output in context before putting it into a public page, imported dataset, or shared plan.
Q: What is the main limit for ui testing?
A: The generator does not guarantee WCAG contrast. Use the output as prompts, placeholders, examples, or test fixtures, and switch to a specialized source when the work is regulated, security-critical, or legally sensitive.
