Random Color Generator (Hex, RGB & HSL Palette Maker)
Generate random aesthetic colors and harmonious 5-color palettes with HEX, RGB, and HSL values.
TL;DR: Random Color Generator creates single colors or 5-color harmonious palettes with instant HEX, RGB, and HSL copying.
How Do I Generate Random Colors for Web Design?
To generate random colors, a color generator calculates random values across the RGB (0–255) or HSL (0–360° Hue, 0–100% Saturation, 0–100% Lightness) color models. It can generate single random colors or apply color theory formulas (analogous, monochromatic, complementary, triadic) to build harmonious multi-color palettes with instant HEX and CSS code copying.

Frequently Asked Questions
- A random color generator is a design utility that produces random, aesthetically balanced colors and color palettes for web design, digital art, UI branding, and styling.
- Click 'Generate Color' or tap your spacebar. The tool generates a random 6-digit hexadecimal code (e.g. `#7B2FF7`) with RGB and HSL equivalents.
- HEX is a 6-digit base-16 code (`#3b82f6`); RGB specifies Red, Green, and Blue light values from 0–255 (`rgb(59, 130, 246)`); HSL specifies Hue angle, Saturation %, and Lightness % (`hsl(217, 91%, 60%)`).
- Yes. Click the padlock icon on any color swatch to keep it locked while re-generating the remaining colors in the palette.
- Yes. The tool automatically displays the calculated WCAG contrast ratio for black vs white text on each color swatch.
- Yes. Click 'Export CSS' to copy formatted CSS custom properties (e.g. `--color-primary: #7b2ff7;`) directly into your project stylesheet.
- Yes. All color math runs client-side using JavaScript with zero latency.
- You can generate Monochromatic (shades of one hue), Complementary (opposite colors on the color wheel), Analogous (neighboring hues), and Triadic palettes.
