Matt, Some where along the line I was told that it is from absorbing moisture with age. I stopped using the stuff that had changed color for anything structural and used it up for micro filler and such so it did not go to waste. I do not know if it harms the integrity of the epoxy, I just did not continue to use it because it didn'tseem right. I used West Systems and am just guessing it would be the same cause.
