XF 1.5 Having a hard time finding where to change these.

My site's www.darkestdawn.black. I've been digging through my template and attempting where to find a couple of things I don't like. Changing my color palette causes other things to look gross, so I am trying to find the exact spot to change the things you see in these screenshots.

See where this gradient is, and also my completely unreadable staff badge? Eww. http://prntscr.com/dklck6

And for the life of me, I can't find where to change this text to white. This also happens on the New Thread button when we go to post a thread. http://prntscr.com/dklcuy

Any help that could be offered would be wonderful!
