Epoxy Turns Yellow in Container???

In this video we go over the issue of epoxy hardener turning yellow in the container before the two parts are mixed together. Is this bad?? will the epoxy still harden correctly? do I have to throw away my epoxy and start over?? what do I do??
these are all great questions that I hope are answered in this video.
If you have any questions feel free to leave them in the comments!!!
