Should it mean anything, significant, other than a possible medical problem, that one's eyes can and do change color(s), based on mood? Now, I am looking for a possible spiritual answer. I don't really think there is a definitive answer to this question because the truth is that nobody knows, which is why I am asking. I don't want medical scientific answers because this question actually pertains to me, and I have looked into it, and it has been this way all of my life. I have no medical problems. Clean as a whistle. Why would my eyes change to a yellowish-light brown, when extremely angry? Then when I am partying and drinking, feeling relaxed, they seem to turn hazel. Why? I know and my friends know, my eyes are light brown, always. At the same time, my friends and family can account for the change in eye color. I don't think any of this has to do with the lighting.
