RGB to HEX Color Converter

RGB describes a color as three numbers from 0-255 for red, green and blue light. HEX packs the same three values into a 6-character code, two hex digits per channel, prefixed with #. rgb(91, 83, 232) becomes #5B53E8 because 91 in hex is 5B, 83 is 53, and 232 is E8.

Both describe exactly the same color — HEX is just the more compact form used in CSS, design tools and most style guides, while RGB is closer to how screens actually mix light.

Where this comes up

• Copying a color picked in a design tool (which shows RGB) into CSS or HTML, which usually wants hex
• Matching brand colors across a style guide that lists both formats
• Reading pixel color values from an image editor and converting them to a web-ready hex code
