I have been a CNC operator in a cabnit shop for years and know about the only thing you can do is call your insurance man and get the process going. Once the finish is gone –it’s gone. sorry
Check to see if it matches the shade of the rest of the counter when it’s wet. I had that happen to me (mine was green also). If so, a little bit of clear acrylic paint (go lightly here) on the stained area will help. For me, it recovered almost completely.
