I'm assuming it's for a story, if so, depends on the character (same for art actually). I know my Saguru is partial to clear glass with colour spirals running through it (it lights up!).

If it's not...again, depends on the person's preferances, if I were into that (I'm not, too er..painful for me), I would prefer black with silver or purple sparkles).

And I think I just out perved you...
