About the Color Picker

A color picker lets you select any color visually and see every representation web and design tools accept: hex codes for CSS, RGB for image editing, HSL for design systems, RGBA/HSLA for transparency. This picker handles 3-, 6-, and 8-digit hex, bounds-clamps invalid RGB/HSL input, and offers one-click copy in every format.

Features

  • Native color picker + text input
  • 3-digit (#FFF), 6-digit (#FFFFFF), and 8-digit (#FFFFFFAA) hex
  • HEX, RGB, RGBA, HSL, HSLA output
  • Copy each format with one click
  • Live preview swatch

How it works

  1. Click the color swatch or type a hex code.
  2. Read the equivalent RGB, RGBA, HSL, and HSLA values.
  3. Copy whichever format you need.

Frequently asked questions

What's 8-digit hex?

+

CSS accepts #RRGGBBAA where AA is alpha transparency (00 = fully transparent, FF = fully opaque). It's the simplest way to express alpha without switching to rgba().

Why do HSL values look wrong after roundtrip?

+

HEX and HSL aren't perfectly mutually invertible due to rounding — you'll see values within ±1 of the original. This is normal.

Is RGB or HSL better?

+

Use HSL when editing (it's perceptually intuitive: hue, saturation, lightness). Use HEX or RGB for storage and CSS.

What's the difference between HSL and HSV?

+

HSL's lightness axis goes from black to white via the pure color at 50%. HSV's value axis goes from black to the pure color at 100%, never pure white. Designers typically prefer HSL.

Does the eyedropper work?

+

Yes, on Chromium browsers. Safari and Firefox don't currently support the EyeDropper API.
