Well heck, as I've noticed a lot of web design never takes Macs into consideration, or disregards the existence of any browser outside IE...
We'll just lump these people in with those other oddballs: Mac users, Opera/NN users, tetrachromants... They all just need to get with the picture, buy a Windows box, use IE, and ditch those funky extra color receptors!
I always wondered about things like that though. What if the color you call blue actually looks like what you call green to me? We'd both call it blue, because that's what we were taught in school... but we'd never see the world the same way. Just be using the same words for completely different colors.
If I looked through your eyes, what if I saw blue apples on trees with vibrant orange leaves (according to me)... and you looked through my eyes and saw yellow apples on trees with blue leaves (according to you), but because of early childhood education, we both *said* we saw red apples on a green-leaved tree? I don't suppose it would really change much of anything would it?
