Tossing this in, but if you want to mess with the color of your karma number, it depends on the amount of karma you have! I actually don't remember all the divisions for the colors, but I thiiink it works something like this:

For 0-49(?) Karma:
.karma_red {color:#fff;}

For 50-75(???) Karma:
.karma_yellow {color:#fff;}

For 75(?)-99.99 Karma:
.karma_green {color:#fff;}

And for above 100 Karma:
.karma_top {
color: #FD9D0B;
text-shadow: 0px 0px 8px #FFDE00;
}

I am wildly guessing what the number ranges are, so take this with a bit of salt. That said, if you want to, say, make your lower than 100 Karma to glow, you could just do, say:

.karma_green {
color:#fff;
text-shadow: 0px 0px 8px #006A8F;
}
