Free Color Converter - HEX, RGB & HSL
Convert colors between HEX, RGB, and HSL formats instantly with a live color preview. Whether you are a web developer writing CSS, a designer specifying brand colors, or just need to match a specific shade, this tool handles all common color format conversions in real-time.
How to Use
Type or paste a color value in any format (HEX, RGB, or HSL) into any input field. The tool automatically detects the format and converts it to the other two formats instantly. A color swatch shows you the actual color so you can verify it visually before using it in your project.
Color Formats Explained
- HEX (#RRGGBB): The standard CSS hex color notation. Each pair represents the red, green, and blue channels as hexadecimal values from 00 to FF (0-255). Shorthand HEX like #FFF maps to #FFFFFF. HEX is the most common format in design mockups and CSS frameworks.
- RGB (red, green, blue): Specifies colors using decimal values from 0 to 255 for each primary color channel. RGBA adds an alpha channel for opacity control (0.0 to 1.0), making it useful for overlays and semi-transparent elements.
- HSL (hue, saturation, lightness): An intuitive format where hue is a degree on the color wheel (0-360), saturation is a percentage (0-100%), and lightness is also a percentage (0-100%). HSL is easier to reason about when creating color schemes - adjust hue for different colors while keeping saturation and lightness consistent.
When to Use Each Format
HEX is ideal for design handoffs and CSS variables. RGB/RGBA is useful when you need opacity control without needing preprocessor functions. HSL excels for programmatic color manipulation - changing hues for hover states, generating complementary palettes, or applying theme variations while preserving saturation and lightness values.
