Not a random color exactly, but here is code I wrote that produces a nice pastel color from any string, and will always be the same for that same string (it actually only uses the first 2 and last letters of the string).
//--- START Helper Functions ------------------------------------------------\\
function Colorize(seed = 'AA')
{//Returns a pastel color based on 1st, 2nd, and Last characters in a string.
if (seed.length = 0) {seed = 'AA';} else
if (seed.length = 1) {seed += 'A';}
r = (seed.charCodeAt(0) * 9).toString(16).slice(-2);
g = (seed.charCodeAt(1) * 9).toString(16).slice(-2);
b = (seed.charCodeAt(seed.length-1) * 9).toString(16).slice(-2);
return '#'+r+g+b;
}
