What is a Random Color Generator?

A random color generator produces random colors — typically as hex, RGB, or HSL values — for design, development, or testing. The Tooladex Random Color Generator lets you choose 1–100 colors, pick HEX, RGB, or HSL output, and use cryptographically secure randomness (crypto.getRandomValues) so each color is unpredictable.

All controls (number of colors, output format, Generate, Copy All) are at the top so you can regenerate or copy without scrolling — even when you have 100 colors. Click any swatch to copy that color’s code. All processing runs in your browser; no data is sent to a server.

How it Works

  • Choose number of colors — Select 1 to 100 from the dropdown at the top.
  • Choose output format — HEX, RGB, or HSL. The grid and Copy All use this format.
  • Generate — Click "Generate" to create a new set of random colors.
  • Copy All — Copy every color’s code in one go (comma-separated).
  • Copy one — Click any color swatch to copy that color’s code.

Randomness comes from crypto.getRandomValues(). Each R, G, and B value (0–255) is chosen independently, so every combination is equally likely.

Use Cases

  • Design inspiration — Get unexpected colors for palettes, backgrounds, or accents.
  • Testing — Generate test data for UI components, charts, or placeholders (e.g. 20 distinct colors).
  • Prototyping — Quickly assign distinct colors to items (tags, categories, statuses).
  • Learning — Explore hex, RGB, and HSL with real examples.

Frequently Asked Questions

Are the colors truly random?

Yes. The tool uses crypto.getRandomValues(), which provides cryptographically secure random numbers. Each R, G, and B byte is chosen independently, so outcomes are unpredictable and uniform over the full color space.

How many colors can I generate?

You can select from 1 to 100 colors. Use the "Number of Colors" dropdown at the top, then click "Generate". All controls stay at the top so you can change the count and regenerate or copy without scrolling.

Is my data sent anywhere?

No. All generation and display happen in your browser. No color values or other data are sent to any server.
