Back to Tools

This color picker lets you choose any color visually, fine-tune it with HEX, RGB, or HSL values, and copy the exact code in the format your project needs. It’s made for web developers writing CSS, designers matching brand colors, and anyone who has ever needed “that exact shade of blue” in usable form.

How to Use

  1. Pick a color: Click the visual picker and drag to find the shade you want
  2. Fine-tune precisely: Type a HEX code, or adjust the RGB channels and HSL values directly
  3. Explore harmonies: Check the complementary, analogous, and triadic palettes generated from your selection
  4. Copy values: Click any format to copy it, ready to paste into CSS or design tools

Features

  • Visual color picker — drag to select any color intuitively
  • HEX, RGB, and HSL with real-time conversion — edit one format, watch the others update
  • Direct HEX input — paste a code to jump to a known color, with validation for typos
  • Automatic color harmonies — complementary, analogous, and triadic palettes built from your pick
  • Live preview and one-click copy — grab any format instantly

HEX, RGB, and HSL: Three Ways to Describe the Same Color

A HEX code like #3B82F6 is just RGB written in hexadecimal: 3B is red, 82 is green, F6 is blue, each channel running from 00 to FF (0–255). It’s compact and works everywhere in CSS, which is why it dominates stylesheets — but it’s nearly impossible to adjust intuitively.

HSL was invented to fix that. Hue is the color’s position on the wheel (0–360°: 0 is red, 120 green, 240 blue), saturation is its intensity (0% is gray), and lightness runs from black (0%) through the pure color at 50% to white (100%). Want a darker button variant? Keep hue and saturation, drop lightness by 10%.

Tips for Picking Colors That Work

Building a palette from scratch? Start with one base color and let the harmony generators do the math: triadic schemes give three balanced accents, analogous schemes give safe neighbors for backgrounds and hover states. Before committing to a text/background pair, run it through a contrast checker — what looks pleasant to you may be unreadable for users with low vision.

Use Cases

  • Web development: Grab HEX or RGB values to paste into CSS
  • UI design: Build a small palette around one brand color using harmony rules
  • Format conversion: Turn an HSL value from a design spec into HEX for production code
  • Brand work: Verify a sampled color matches the official brand code exactly

Frequently Asked Questions

What color formats are supported?

HEX, RGB, and HSL formats are supported with real-time conversion between all three.

Can I enter a color code directly?

Yes, you can type a HEX value into the input field to jump straight to a specific color, and invalid codes are flagged with an error message.

What are complementary, analogous, and triadic colors?

They are classic color-wheel harmonies. Complementary colors sit opposite your chosen color, analogous colors sit next to it, and triadic colors are evenly spaced 120 degrees apart. The tool generates all three palettes automatically from your selection.
