Do HEX, RGB, and HSL show different colors?
No. All three values are derived from the same generated red, green, and blue channels. They are different notations for one color.
Random Color Generator
Generate one random color with matching HEX, RGB, and HSL values.
How the random color generator works
The generator securely selects red, green, and blue values from 0 to 255. It converts that single RGB color into uppercase HEX and rounded HSL display values, so every format stays consistent.
How to generate a random color
- Select Generate Color to create a new sample.
- Review the swatch and all three text formats.
- Copy exactly the HEX, RGB, or HSL notation you need.
Ideas for using random colors
- Explore a new direction during a design exercise.
- Fill mockups with varied placeholder colors.
- Practice UI contrast checks with unpredictable backgrounds.
- Set constraints for a drawing or creative prompt.

Frequently asked questions
How is the preview text color selected?
The tool calculates WCAG relative luminance, compares the contrast ratios for black and white, and uses the stronger option.
Does the generator keep color history?
No. Only the current result is shown, and resetting or leaving the page clears it without saving a history.
