Hey there!
We both could support each other?
'cause I can hook into your plugin and check for the separator value & you could hook into ColorMe to get the color (like you did it for suffix/prefix)

Would look like this:

Plugin colorMe = getServer().getPluginManager().getPlugin("ColorMe");
if (colorMe != null) {
colorMe.getColor(PLAYERNAME);
}

Would be awesome :)
