@ mitchi: They're the same sprite, only the first has glasses with a blue rim -which looks blue on the sprite. I guess you have to zoom in to see it, though, or remember the good old 2K RTP XD. I didn't edit the glasses because they fit the sprite colors imo. I might change the eye color to brown, though. It's a simple edit.
That's not always the case... Yes, the frame is blue, but what about the actual lenses? Are they blue too? Nope, they are transparent.
Check out the female scholar sprite again. Her eyes are kinda blue. hehe.
