Need help formatting buttons on sliders

I recently installed the Construction Field theme on my WordPress site because I’m building a new demo site for my company. I know a little CSS but I’m not proficient at it by any means.

I would like for BOTH the buttons on the two main sliders to go transparent green on hover. I was able to change Button One like so:

.btn-primary.btn-reverse:hover {
background: rgba(0,255,0,0.2);
}

But the other button goes solid blue on hover, and I can’t find where to change that!

The site’s not public yet, so I can’t include links. But any general advice would be appreciated.
