The normal color of home made Fina is gold or yellowish color. I'm sure there is nothing wrong with it. You also dont need to bake it. The filter will trap any bacteria and you'll end up with a sterile product, provided that you were at least careful during the procedure. I've dreamed about making many bottles of Fina and I never baked a single one, and I never dreamed about having a single infection or any other problem.
Hope it helps,
