How do you change players' EYE COLOR?

I thought that the eye color attribute was located in the appearance_info.RDAT file--but apparently it is not located there. I also didn't see an editable eye-color attribute when I opened my ROSTER with Limono Trainer... If anyone has a moment, would they mind instructing me where you change a player's eye color please? Thank you greatly in advance!

...just checking, since its been a week now... Is this not possible; too difficult to explain; unsolved yet; so simple that I'm a jackass for asking; all of the above? Please let me know... Thanks

No it's not possible through in-game features. You would have to do it through hex editing which is only possible through memory editing with Cheat Engine.
