Social share button – Twitter color

In my last (and first) post here, I complained about the Twitter symbol “X” being out of alignment in the round version of the “social share” button. You guys responded to me with a code to correct the positioning of the logo (it worked btw).
I thought this would be fixed in the next update (which was released today) and it wasn’t*

Other than that, I wanted to know if it is possible to change the color of the button (just the “X” button) to black, which is the color of the social network. It is no longer blue and tbh only this theme chose to keep the old color for no reason at all.

Thanks in advance
