Kingdom Hearts II Yellow eyes

I searched the forums and I don't think this has been discussed yet. Correct me if I'm wrong. Also, there may or may not be spoilers, because I talk a little bit about Birth By Sleep as well.

As I was making an AMV, I was messing around with the scene where Terra looks up (very mean-like) at Kingdom Hearts. I put an effect on the clip which noticably intensified his eye color. I realized that his eyes were blue, he blinks, and his eyes change to yellow. Mind you, I thought his eyes were only yellow. Now, I do want to know why his eyes changed color as he looked at Kingdom Hearts, but I also remember that many of the Nobodies and so forth have yellow eyes. Does anyone know why they have yellow eyes, or has a theory about it? Also, if you could get a list of characters with yellow eyes, and a picture of them, I can make a list below.

Characters with yellow eyes:
Terra
Master Xehanort
Saix
Xemnas
Xigbar
DiZ

(Unfinished list)

wierd i never notcied that really except for xemnas saix and xigbar

 

Woh..... that was weired, how could i not ahve noticed that, my theory is that they all have on contacts 0.0 ooweeoo

 

contacts???

 

How would Terra put on his contacts that fast, then? xD​

 

exactly XD

 

Umm, he used the magic spell freeze on the camera, puts them in, then magic spells fire on it and wala!

 

but didn't it turn yellow with fading unless there special contacts

 

Ok here it goes again.... He used the magic spell stop, goes 2000 years into the future, invents the magic spell "GO Back", and while he's there he buys yellow contacts that dont fade and are magic, He then goes back, unfreezes the camera And WALA!!!!

 

Or maybe he just used a special yellow version of Sharingan that he learned while visiting Naruto's world.​

 

thats wat happend

 

oh double teaming me aye? You'll pay for that! I now summon my YELLOW CONTACTS!!!! taste my fury crackers!

 

shut it ***** boosh magic

 

I'm not sure as how to take that? Racist?

 

That means Saix and Xigbar and the rest have Yellow Sharingan too. xD​

Wate, im caucasian, its just some random thing i say........... i dont know why but i didn't medan that to seem racist, as it would apply to me as well, except im a saltine
