HEX, RGB and HSL — what's the difference?
HEX (#ff0000) is the most common notation in web design. RGB (255, 0, 0) stands for red, green, blue values. HSL (0, 100%, 50%) describes color via hue, saturation, and lightness.
Web developers frequently need to convert between HEX (#FF5733), RGB (255, 87, 51), and HSL (9, 100%, 60%) color formats. Designers working with print materials need CMYK values for accurate color reproduction.
This converter supports all major color formats including HEX, RGB, RGBA, HSL, HSLA, and CMYK. Enter a value in any format and instantly see the equivalents in all other formats.

Understanding Color Formats
HEX codes (#FF5733) are the most common format in web design and CSS. RGB (255, 87, 51) defines colors by red, green, and blue channel intensity and is used in CSS and image editing software. HSL (14, 100%, 60%) describes colors by hue, saturation, and lightness, making it the most intuitive format for adjusting colors — changing lightness makes a color lighter or darker without shifting the hue.
When to Use a Color Converter
Use this converter when working with colors across different contexts: web development (HEX to RGB for CSS), graphic design (RGB to CMYK for print), data visualization (HSL for perceptually uniform color scales), and brand guideline creation (documenting colors in all formats). It is also useful when matching colors between digital screens and physical print materials, where CMYK values ensure accurate color reproduction.
Common Use Cases
- •Convert a brand's HEX color to RGB for use in CSS rgba() functions with transparency Color Converter — HEX, RGB, HSL & CMYK
- •Get CMYK values from a web color for accurate print reproduction
- •Convert between HSL and HEX when adjusting color lightness or saturation in CSS
- •Document brand colors in all formats (HEX, RGB, HSL, CMYK) for a style guide
- •Match a color seen in a design tool (RGB) to its CSS equivalent (HEX or HSL)
Expert Tips
- ✱Use HSL for intuitive color adjustments — change lightness to make colors lighter/darker, saturation to make them more vivid/muted, without shifting the hue
- ✱For print projects, always convert to CMYK — RGB colors displayed on screens often look different when printed because screens emit light while printers use ink
- ✱When specifying colors with transparency, use RGBA or HSLA rather than HEX — the 8-digit HEX format (#RRGGBBAA) is less intuitive and harder to read
Frequently Asked Questions
- HEX is a compact notation for RGB values using hexadecimal numbers (e.g., #FF5733). RGB specifies red, green, and blue channel intensities from 0-255. HSL describes colors by Hue (0-360°), Saturation (0-100%), and Lightness (0-100%). HEX and RGB represent the same information differently, while HSL is more intuitive for humans to work with.
- Use RGB for anything displayed on screens (websites, apps, digital media). Use CMYK for anything that will be printed (business cards, brochures, packaging). Screens emit light (additive color mixing), while printers use ink that absorbs light (subtractive color mixing), which is why the same values produce different results.
- Use this converter by entering RGB values or HSL values, and it will show the corresponding HEX code. You can also use browser developer tools (right-click > Inspect) to see HEX codes of any element on a webpage, or use color picker tools in design software like Figma or Photoshop.
- Alpha is a fourth channel (0-1 or 0-255) that controls transparency. An alpha of 1 (or 255) means fully opaque, while 0 means fully transparent. In CSS, you can use rgba(255, 87, 51, 0.5) for 50% transparency, or the 8-digit HEX format like #FF573380.
