I just toyed with the hue and saturation, is all. Besides, unless you're staff or are Tier 6 you couldn't put it in your usertitle (and with non-staff it's a little tricky since we can't [img][/img]).
I imagine those things could definitely have other uses, such as what Matt did with the image in his signature. :p
Yeah, it's pretty cool how you managed to recolor the userbar. I wonder if you plan on doing the same with the other ones i.e. Tier 1/2 with silver userbars, Tier 3/4 with gold and Tier 5 with crystal blue. It'd be pretty nice to see how great your talent is.
