After UI update, class='Vibrant Success' button is blue instead of green. How can I make the button green again?

I agree with Dan.  We would like our Green back please without me needing to survey all my clients to ask if they have any buttons which are now blue which they seem to recall used to be green.  I would not bother doing that so that they will just stay blue unless someone complains.  But that is a very nuanced thing to notice that inconsistency.
