Black buttons look out of place

Question

I'm referring to those new big black buttons on Stack Overflow for actions such as "Post Your Answer", "Add Comment", "Add Another Answer", "Yes" and "No":

Their high contrast and relief hurt the eye in an interface otherwise mostly soft.

The problem with spots of high differences of contrast is that it makes more difficult to see the rest of the page.

Answer 1

UserScript to bring back the plain button.
