I wouldn't bother too much about lenses. I have kind of a contact lens phobia and completely refrain from wearing them. As long as your character's got a natural eye colour most ppl won't notice anyway. My eyes are grey-green and I cosplayed Dino (brown eyes) afterall.
Even when I did G. (and he's got red eyes afterall) or Lal (red as well) no one complained.
Of course it's nice to have the right eye colour, but it isn't the most essential either except if the eyes are very characteristical as in case of Mukuro for example.
Besides I'm curious. Which version of Gokudera have you planned, Sokmunki?^^
Gokudera Hayato (TYL - Colore Artwork) (KH Reborn!)
Also upcoming this or in the beginning of next year:
Young Griff (A Song of Ice and Fire - A Dance with Dragons)
