How to convert RGB to HEX
- Type the RGB value into Color: rgb(30, 144, 255), or just the three numbers separated by commas.
- The HEX code appears at the top on the right.
- Click the HEX value to copy it.
Why HEX codes are everywhere
HEX codes are short, easy to copy and the same in every tool, so brand guides, CSS and design apps use them as the common format. RGB is how screens actually make color, mixing red, green and blue light, and image editors usually show both.
Values outside the range
Each RGB channel runs from 0 to 255. Numbers above 255 are treated as 255 and negative numbers as 0, the same way browsers handle them in CSS.
