The Ultimate Developer's Guide to Color Models (HEX, RGB, HSL)
Welcome to our free, fast, and secure Color Converter. This tool is an essential utility for web developers, UI/UX designers, and digital artists. It provides an intuitive online color picker and instant, two-way conversion between the three most important color models used in web design: HEX (Hexadecimal), RGB (Red, Green, Blue), and HSL (Hue, Saturation, Lightness).
This color code converter is 100% client-side, meaning all calculations happen securely in your browser. No color data is ever sent to our servers, ensuring your work remains private. Whether you need to convert HEX to RGB, find the HSL value of a HEX code, or convert RGB to HSL, this tool is your one-click solution.
Core Tool Features
Use the built-in color picker to find the perfect shade and get all its codes.
Change any value (HEX, RGB, or HSL) and all other fields will update in real-time.
All conversions happen in your browser. No data is ever uploaded.
Understanding Web Color Models
To master web design and development, you must understand the different ways we tell a computer what color to display. This tool converts between the three most important models: HEX, RGB, and HSL.
1. RGB (Red, Green, Blue): The Additive Model
The RGB color model is the foundation of all digital displays. Your monitor, phone screen, and TV all create colors by mixing different intensities of **R**ed, **G**reen, and **B**lue light. This is an "additive" model, meaning you start with black (no light) and *add* light to create color.
- Each color (R, G, B) is given an intensity value from 0 (off) to 255 (full intensity).
rgb(0, 0, 0)is pure black (all lights are off).rgb(255, 255, 255)is pure white (all lights are at full intensity).rgb(255, 0, 0)is pure, bright red.
In CSS, you can also use RGBA, which adds an 'Alpha' (transparency) channel: rgba(255, 0, 0, 0.5) would be a 50% transparent red.
2. HEX (Hexadecimal): The Developer's Shorthand
A HEX color code is simply a different way of writing an RGB value. It is the most common color format you'll see in HTML, CSS, and design software. A HEX code is a 6-digit (or sometimes 3-digit) string preceded by a hash (`#`).
It works by representing each of the RGB values (0-255) as a two-digit hexadecimal number (00-FF).
- The first two digits are for **R**ed (00 to FF).
- The middle two digits are for **G**reen (00 to FF).
- The last two digits are for **B**lue (00 to FF).
For example, `rgb(255, 102, 0)` is converted like this: 255 = `FF`, 102 = `66`, 0 = `00`. The resulting HEX code is #FF6600. Our RGB to HEX converter does this math instantly.
3-Digit HEX Shorthand: If both digits for a color are the same, you can use a 3-digit shorthand. #FF00CC becomes #F0C. Our tool provides the standard 6-digit code for maximum compatibility.
3. HSL (Hue, Saturation, Lightness): The Intuitive Model
The HSL color model is by far the most intuitive for humans because it aligns with how we *think* about color. Instead of mixing light, you "pick" a color and then adjust its intensity and brightness.
- Hue (H): This is the pure color, represented as an angle (0 to 360) on a color wheel. 0° is red, 120° is green, and 240° is blue.
- Saturation (S): This is the intensity or "purity" of the color, as a percentage. 0% is completely desaturated (a shade of gray), and 100% is the full, vivid color.
- Lightness (L): This is the brightness of the color, as a percentage. 0% is always black, 100% is always white, and 50% is the "purest" version of the color.
This model is a favorite of designers and CSS developers for creating themes. Need a hover state for a button? Just take its HSL value and decrease the Lightness by 10%. Need a disabled state? Decrease the Saturation by 50%. Our HEX to HSL and RGB to HSL converters make this easy.
How to Use Our Color Converter Tool
Our tool is designed for seamless, two-way conversion.
- Use the Color Picker: The easiest way to start is to click the large color swatch at the top. This opens your browser's native color picker. As you move the selector, the HEX, RGB, and HSL values will all update in real-time.
- Enter a HEX Code: Type or paste any 6-digit hex code (e.g., `#34A853`) into the HEX input. The RGB and HSL fields will instantly update.
- Enter an RGB Value: Type an RGB value (e.g., `52, 168, 83`) into the RGB input. The HEX and HSL fields will update.
- Enter an HSL Value: Type an HSL value (e.g., `141, 52, 43`) into the HSL input. The HEX and RGB fields will update.
- Copy Any Value: Click the "Copy" button next to any format to instantly copy the code to your clipboard.
This real-time, bi-directional conversion makes our tool a powerful color calculator for any design or development task.
