I was looking through some used Fizzies online and I noticed that some of them had the gems in their eyes more brightly colored (which tbh I found kind of creepy, like a deer caught in headlights or something) while in others the gems were significantly darked and made the eyes more natural looking. Which of them is the original shade? I guess that either one of them is a result of fading or the other of staining over time, but which one is it? The wiki has pictures of both so it's not exactly helping. Or maybe those are just two different regional variants?
