) if that's less complicated. In fact, a colour from a 'web-safe' palette would be ideal.

    for (var i = 0; i < str.length; i++) {
       hash = str.charCodeAt(i) + ((hash << 5) - hash);
    return hash;

function intToRGB(i){
    var c = (i & 0x00FFFFFF)

    return "00000".substring(0, 6 - c.length) + c;

To convert you would do:
