I can see it without squinting or turning it. I could see it with the cassette still in tact, although I took it apart to try for a pic. It's not only visible in certain lights. My DH can see it too! There is definitely color to it. A tweaked version to try and better illustrate. I didn't add anything. I just changed the saturation & brightness. Obviously a close up! LOL This is the same test, but not close up. It's still the tweaked version but also gray scaled. Here's the kicker... I don't know if it came up in the allowed time. I looked at it for less than a minute this morning and tossed it aside. Tonight, I had some weird desire to check it, and this is what I found. I've never had an evap like this before. I really don't quite believe it, but I don't know.
