Sure in this "extreme" I'll agree, it was just an experiment after all (I do think both the short-hand classes and attributes look wrong). Do you think the same about either of these?

    <Button color="red">Hello</Button>
    <Button red>Hello</Button>

What does red apply to? The button color? The text color? Both (sounds useless)?

If you told me a button were red, I would assume the button is red and any decoration on it (e.g. text) isn't. Not sure if that's what happens here.

I dislike both of these :). Just leave the styling layer to itself.
