Dye Previews

Now I know that the idea of dye previews isnt a very original one but I just feel that I would like to voice my opinion !.I feel sorry for people who spend there hard earned cash on some brilliant dye concoction and it turns out to look like cowpat on there armour.I mean what have arena net got to lose with putting this sought of preview system in ?.Could they not just have something when you talk to the dye trader a 3d of your character like the one in you inventory apears and you can try the dyes and mixes before you buy ?

I dont think this is a good idea. This game is allready easy enough. Dyes dont cost to much either, exept for black.

thats exactly what I mean
