What RGB to HEX Converter does

The RGB to Hex Converter turns red/green/blue values (0-255 each) into a six-digit hex color code, and back again, updating a live color swatch as you adjust any field. It's built for anyone who needs to move a color between a design tool that outputs RGB and code or CSS that expects hex — just numbers typed in your browser, no image upload required.
