My eyes are brown now and they've been brown in a few past lives. But I know they've been blue in at least one.
By the way, I have an eyes-related story to tell!
I have a friend who likes to exchange cell phone photos with me. Often we draw over the photos leaving nothing but the eyes visible. Sometimes we leave the mouth. It depends. But, basically, we like to partially obscure ourselves when we send photos. (Difficult to explain but we find this humorous for some reason and we do it almost every day)
Anyway, as I received one of those photos from her, I had the brilliant idea to try to take a photo of a certain portrait of me from a past life and draw over it as we always do...and then send that photo in exchange. So, I took a close up photo of the portrait and was surprised to find...it looked rather lifelike in the photo. When I drew over it, I left the eyes and the mouth visible.
She received it and absolutely assumed it was me. She saw no difference and thought I had just taken a photo of myself! I've never told her about the past life at all. She doesn't even know that I believe in past lives, has no idea about it and she's never seen that portrait before. I then told her I sent her a photo of an old portrait and she responded, "No way! I thought that was you."
I actually had blue eyes in that life but they appear darker when the portrait doesn't have good lighting. What you can see is, essentially, the same "spirit" inside of my eyes. It's strange. The face overall isn't exact but it has the same "feel". It's just so fascinating to me that reducing the portrait largely down to the eyes and mouth caused my friend to immediately identify, without question, that it was me.
