HEX, RGB, and HSL color converter for web design
In web design and frontend development, colors are represented in different models depending on the context. The HEX format (#RRGGBB) is the most commonly used in CSS stylesheets for its brevity. The RGB model (Red, Green, Blue) defines colors through the additive mixing of red, green, and blue with values from 0 to 255, and is the native model for digital screens. HSL (Hue, Saturation, Lightness) organizes colors more intuitively for designers.
Our converter transforms any color between these three formats in real time. This is especially useful when working with design tools like Figma or Adobe XD that export colors in HEX, but you need RGB values for JavaScript animations, or when you want to create color variations by adjusting only the lightness in HSL.
You can enter values manually in any of the three formats or use the browser's native color picker to choose visually. Each format includes a copy button that places the value on the clipboard ready to use in your CSS, JavaScript, or any other design tool.
Frequently asked questions
What is the difference between HEX and RGB?
Both represent exactly the same colors, only the notation changes. HEX uses hexadecimal numbers (base 16) in #RRGGBB format, while RGB uses decimal numbers from 0 to 255 for each channel. For example, white is #FFFFFF in HEX and rgb(255, 255, 255) in RGB. HEX is more compact for CSS, while RGB is easier to manipulate programmatically.
When should I use HSL?
HSL is ideal when you need to create harmonious color palettes or variations of the same hue. By separating the hue (H) from saturation (S) and lightness (L), you can create lighter or darker versions of a color by simply adjusting the lightness, or more vibrant or muted versions by changing the saturation, without altering the base hue.
What color model do browsers use?
Web browsers understand all three formats: HEX, RGB, and HSL in CSS. Internally, screens work with RGB since each pixel is composed of red, green, and blue subpixels. However, modern CSS also supports more advanced models like oklch and display-p3 for wider color gamuts on HDR displays.
