Random Color Generator

Generate random colors instantly and copy HEX, RGB and HSL values. Create individual colors or random palettes for design and development.

Palette size 1 color or a palette of up to 10.

Colors are generated locally from secure random bytes using the browser Web Crypto API.

How to Use

Choose how many colors you need, from 1 to 10.
Press Generate colors to create the palette.
Use the copy buttons to grab HEX, RGB or HSL for a single swatch.
Press Copy all HEX for the whole palette, or Generate again for new colors.

How It Works

A color is three numbers: red, green and blue, each from 0 to 255. The generator draws each channel with a secure random integer from crypto.getRandomValues(), producing uniformly random colors — every possible RGB value is equally likely. HEX and RGB output encode those channels directly; HSL is computed from the same values using the standard conversion (undefined hue for grayscale is reported as 0°).

Because each palette color is independent, generated palettes are eclectic rather than deliberately harmonious. That makes them useful for finding unexpected combinations, generating test data, or picking a starting point you then adjust in a design tool. Copying always copies the displayed value; nothing is rounded differently from what you see.

Generation happens entirely in your browser, and swatches are drawn with SVG fill attributes, so no third-party asset or style is involved. Because it doubles as a random HEX color and RGB generator, you can copy whichever format your codebase expects.

Examples

Single color: palette size 1 → one swatch like #3F8AC2 with matching RGB and HSL values.
UI palette draft: 5 colors to explore accent options for a layout.
Placeholder colors: 10 colors as test data for charts and dashboards.
Design prompt: generate a palette, then build a color scheme around the boldest swatch.

Common Uses

Finding color inspiration for websites, apps and presentations.
Generating placeholder colors and test data for charts, graphs and UI states.
Picking random accent colors for demos, prototypes and classroom exercises.
Creating varied swatches for art, crafts and design practice.

Frequently Asked Questions

How are the colors generated?

Each color is three independent secure random bytes — one for red, green and blue. The tool then derives HEX, RGB and HSL representations from the same value, so all three formats always describe the exact same color.

What is the difference between HEX, RGB and HSL?

HEX and RGB encode the same red/green/blue mix; HEX is compact for CSS and design tools, RGB is explicit in code. HSL expresses hue, saturation and lightness, which is easier for building tints and shades by hand.

Can I generate a palette instead of one color?

Yes. Set the palette size from 1 to 10 colors. Each color is generated independently, which produces varied palettes rather than harmonious ones; treat them as starting points.

How do I copy a specific format?

Every swatch has Copy HEX, Copy RGB and Copy HSL buttons that copy only that representation, plus Copy all HEX for the whole palette.

Are colors free to use?

Yes. Random color values are not copyrightable, and the tool grants no rights over them anyway — use them in designs, code and prototypes freely.
