What this tool is for
Design tools tend to hand you RGB while stylesheets, brand guidelines and most documentation want HEX. Enter the three channel values, or paste a whole rgb() string, and get the code back with the alpha channel folded in if you supplied one.
How to use it
- Enter the red, green and blue values, or paste an rgb() string.
- Read the HEX code and the other notations.
- Copy what you need.
Frequently asked questions
Can every RGB colour be written as HEX?
Every 8-bit RGB colour, yes: the two notations describe the same values in different bases. Wide gamut colours written in newer CSS colour spaces have no HEX equivalent.
