Change Link Color in H2 Headings

Hey there,

I have recently noticed that the links in headings of my website pages are black instead of the usual blue ( screenshot: http://prntscr.com/rgbm5v ). I have tried many things but haven't been able to change it to blue again. The regular text paragraph links are blue, which is making this problem even more difficult to identify. Also, I use Thrive Architect page builder along with the generatepress theme.
