+1 on the recommendation to just paint it if you want something other than white (Krylon Fusion, neither Home Depot or Rona carry it, but Canuck Tire does). I went and bought black eggcrate once, not only did I have to special order it from some obscure specialty shop (don't even remember who anymore
) but it took a couple weeks to come in and was like $20 per sheet. Whereas white is, what, $3 each or thereabouts. So lesson learned there..
