Having .hasClass / .removeClass support regex has been discussed before,
there is a ticket open for one of them so it might be a possibility.
I don't see much use for replaceClass, rather I think the semantics of
reading it would be a little confusing. I can't even understand what the
code you have there is even supposed to do.
I see no reason to combine add and remove into one.
Just a quick tip, if you're trying to do boolean stuff:
$(node).filter('.color-black').removeClass('color-black').addClass('color-white').end()...
That there would replace color-black with color-white but only for nodes
with color-black, the .end() returns back to the original $(node) so
chaining can continue.
