About colour name finder
Designers and developers often have a HEX code but need a name to talk about it. The finder matches a colour to the closest standard CSS colour name.
How the closest name is found
The tool measures the distance between your colour and the list of named CSS colours and returns the nearest. An exact name appears only if your colour is one of the standard ones, otherwise the answer is approximate.
Where names help
Design handoff notes, accessibility descriptions, documentation and communicating with people who do not read HEX codes.
A worked example
The colour #FF6347 is exactly the CSS name tomato. The colour #FF6648 is not a named colour, so the tool reports the closest one, which is still tomato, because the two are only a few steps apart in red, green and blue.
Names are a communication aid
CSS defines about 140 named colours. They are good for notes and conversations, such as telling a colleague the button is steel blue. For production design, always use the exact HEX code, because two different shades can share one nearest name.
