Same letter different colors

[panfanky]

Hi,
it seems to me the plugin is designed to give same letter the same color, although it is a different username. I think it's better to make the color dependent on something else than the first letter - same color of two different initials can cause no confusion, but what can cause confusing the users is the same color of the same letter.
I propose (made this for myself as a workaround) changing around line 76
this:

var colorIndex = Math.floor((c.charCodeAt(0) + settings.seed) % colors.length);
to something like this:
var colorIndex = Math.floor((settings.name.charCodeAt(1) + settings.name.charCodeAt(3) + settings.seed) % colors.length);
