How the conversion works
A HEX color is the three RGB numbers written in base 16, two digits each. Convert each channel to hexadecimal and join them after a # sign.
Example: rgb(255, 87, 51). 255 is FF, 87 is 57 and 51 is 33, so the HEX code is #FF5733.
Tips
- A channel value of 0 becomes 00 and 255 becomes FF.
- Values outside 0 to 255 are limited to that range.
- When both digits of each pair match (like #FFAA00), CSS lets you shorten the code to #FA0.
