No, Elk is right... and he's pointing out exactly what I was trying to show, it's the whole reason I brought the animation into the thread

Edit:
To show it a little better I whipped this up.

From one frame to the next it doesn't look too bad, I tried bumping up the contrast and watching the animation as a whole but it isn't very drastic. If you look at the change that happens over time, though, you'll see that the wing goes from being very light to very dark.
