I would guess because TD.blue will only affect TD elements with class
blue. Then if you have

.blue { color: blue }

you won't get unexpected effects to do with the border changing on other
elements.

They aren't necessary. (However it might be worth pointing out that some
syntax-colouring editors don't really understand how literals work. In
any case it's possibly arguable that stylistically it's a little clearer
to quote them.)
