About color formats

HEX is compact and common in CSS. RGB describes red, green, and blue channels from 0 to 255. HSL describes hue, saturation, and lightness, which can be easier for adjusting palettes.

Use the live preview to check a color quickly, generate a random color, then copy HEX, RGB, and HSL values into CSS, design docs, UI specs, or bug reports.

Practical color examples

CSS handoff: convert #5eead4 to RGB or HSL when a design note needs all three formats.

Palette tweaking: adjust the HSL lightness value to create hover, border, or disabled states from the same base color.

Debugging screenshots: paste a sampled HEX value and copy the matching CSS declarations for a quick reproduction.

FAQ

What is the difference between HEX and RGB?

HEX is a compact CSS notation, while RGB lists the red, green, and blue channel values from 0 to 255.

When is HSL easier to use?

HSL is useful when you want to adjust hue, saturation, or lightness without thinking in raw RGB channels.

Can I paste three-digit HEX colors?

Yes. Three-digit values such as #fff expand to six-digit HEX values.

Why do converted color values round?

Some RGB to HSL conversions produce decimals. The tool rounds values so they are easier to copy into CSS.
