Calculate Color Proximity

Hi,

I want to compare 1 color (hex or rgb) with a list of colors and choose the more similar of the list.

For example I have #FF1202 and an array with:

array ("FF0000", "00FF00", "0000FF" ...);

I need to find the color more similar in the list (in this case the first: FF0000).


Anyone has an idea?

Thanks

Take a look at this:

Download the example and script and see if you can use it.
I think it not only lets the user know if their color is "safe" or not,
but also provides the nearest safe color ... similar to what you are doing?

Thank you, I'll check this. :)
