replace() for translating color names
You're mixing up data and logic. Separate your replaces into an associative array and iterate over that instead: (My JS is extremely bad, so this will be more pseudocode-ish)

var associations;
associations['/brun/i'] = "Brown";
associations['/sort/i'] = "Black";
//add all the other associations and then

associations.forEach(runReplace);

function runReplace(value, regex, array) {
   color.replace(regex, value);
}


Additionally I suggest you (just like me here) use the Array.prototype.forEach() when iterating over your colors
