I need help changing the font color in gallery captions

[DaveServo]

I have no idea which theme I'm using. I set up this site a couple of years ago at least and changed a few minor things in the code but it's technically custom. I did find a solution via search that had someone placing code directly into the caption text which changed the color but overwrote something somewhere that forced the font back to the original default style (I had changed the font in the theme settings). I seem to remember something having to do with fancy box which I found but changing the color there didn't have any effect. Any ideas?

I'm the OP (DaveServo) but Weebly has mixed my login details up with another account I use so it's no longer possible for me to login with that name. Anyway, the link goes to the solution I mentioned above which does not work for me. It does change the color but it also blocks the font change I made.
