I just baked some jigs for the first time. My problem is that it changed some of the colors. My blaze orange which was a bright flourscent orange now looks more like burnt orange and two of them actually turned brown. The sapphire blue darkened more and now it does not sparkle like before I baked. I am assuming that maybe I need to lower the heat or bake for 15 minutes instead of 20. I baked these at 350 degrees for 20 minutes. I need to know what to do to solve this problem.
