As we've seen, orange or yellowish eyes usually signify that the person has experienced dangerous amounts of darkness. However, is it just darkness or is it something else? As we've seen both Braig and Isa had normal colored eyes, but somehow their eye colors change to orange. Many people assume this is because they fell to darkness, but doesn't KH3D prove that theory wrong? The scene where it zooms in on Braig's orange eye and he claims he is already half Xehanort is the proof. I believe orange eye color represents a piece of Xehanort's heart taking over someone. It makes sense if you think about it. Every person with this eye color is a part of Xehanort: Braig, Isa, "Ansem", Xemnas, and YMX. All members of the new Organization. The two exceptions are Vanitas and Ansem the Wise. They both have orange eyes and don't appear to be part of Xehanort. However, who's to say they aren't? Xehanort created Vanitas so it would be extremely easy for him to place a piece of his heart within the boy. As for Ansem, his first chronological appearance is at the end of BBS where he finds and rescues Terra-Xehanort. At this point in time he has orange eyes. But according to the theories of others, orange eyes are caused by darkness. At this point in time, Ansem had not been banished to the darkness or used the darkness in any manner. My theory is that Xehanort met Ansem during his time in Radiant Garden when he made his plans with Braig. He somehow placed a piece of his heart within Ansem at this time, causing his eyes to change. Another reason darkness can't cause the eye color change is Riku. He wore a blindfold because "his eyes couldn't lie". Many assumed this was because the darkness had changed his eyes to orange, but as we see in 358/2 Days, this isn't the case. He briefly removes the blindfold showing his normal colored eyes. If my theory is correct, Ansem the Wise and Vanitas are members of the new Org. Thoughts?
