The really dumb thing about writing 'color' instead of 'colour' is that you made it even more inaccurate. It should be culler. Which, conveniently, has a u.
Whenever I see 'color' I think of colon as well. Just out of curiosity, do you guys have the same sounds (aside from the r and n) when you say those two words?
Don't even get me started on the fence, defence, defense issue. Totally inconsistent. It should be fence and defence or fense and defense. The words, apart from the 'de' (which can be said in two different way depending on what definition of defence you are using), are said in exactly the same way.
I think a European said it best when he looked at both languages and said that English is all messed up and American English messed it up even more.
