Convert between HEX, RGB, and HSL with a visual picker.
#3B82F6rgb(59, 130, 246)hsl(217, 91%, 60%)🎨 Use the color picker or type any format — converts to all three instantly. Common for web design, CSS, and brand guidelines.
What Is This Tool?
Colors on the web are described in three main formats: HEX (like #3b82f6), RGB (like rgb(59, 130, 246)), and HSL (like hsl(217, 91%, 60%)). This tool converts between all three instantly — type any format or use the visual color picker.
The Three Color Formats
- HEX — six hex digits (#RRGGBB), each pair is a color channel 00-FF. Most common in CSS and design tools.
- RGB — three decimal numbers 0-255 for red, green, blue. Easier to read programmatically.
- HSL — hue (0-360°), saturation %, lightness %. Most intuitive for humans — "make it darker" means lower lightness.
When to Use Which
HEX is the default for CSS and most design tools. RGBis useful when you need to manipulate channels in code or add alpha transparency (rgba). HSL is best when adjusting colors intuitively — creating variations of a hue is much easier in HSL than HEX.
Common Colors Reference
- White: #FFFFFF / rgb(255,255,255) / hsl(0,0%,100%)

- Red: #FF0000 / rgb(255,0,0) / hsl(0,100%,50%)
- Blue: #0000FF / rgb(0,0,255) / hsl(240,100%,50%)
- Tailwind blue-500: #3B82F6 / rgb(59,130,246) / hsl(217,91%,60%)
Frequently Asked Questions
What about alpha transparency?
HEX uses 8 digits (#RRGGBBAA), RGB becomes rgba(r,g,b,a), HSL becomes hsla(h,s%,l%,a). The alpha value is 0-1, where 0 is fully transparent.
