Chancellor Palpatine with normal eye color in Revenge of the Sith when he reveals his true self to Anakin Skywalker.

enter image description here

Chancellor Palpatine a little later in the same movie with yellow eyes, right after he kills Mace Windu. This is maybe just an hour or two later in the character's time.

enter image description here

His eyes appear normal again in later cartoon shows, so he can change it back at will.

What causes his eyes to change color? I would have guessed strong emotions or when he uses Dark Side powers, but neither of those are supported by other scenes from the same movie.

Anakin with yellow eyes shortly after he killed the Separatist leaders.

enter image description here

We see Anakin's eyes go from yellow to normal in a short time. He should have been at the height of his Dark Side powers at this moment, and also feeling the strongest dark emotions since he is plotting to kill his best friend. This was right before he tries to jump to land and gets his limbs sliced off.

Is there a consistent explanation for eye color of Sith Lords? Please provide answers from canon sources.

  • Found this reddit thread about why most sith's eye change colour. In addition (wookiepedia)[] details that The eyes of some Force-sensitives changed from their original colors to shades of fiery red-rimmed yellow, orange or red when they were deeply immersed in the dark side of the Force.

  • The dark side of the Force fuelled by pure hate and anger?

  • @Essen If it was the dark side fueled by pure hate and anger, then wouldn't Anakin's eyes be bright yellow in the last picture above? Instead they are brown.

  • @RichS Yes, you're right. In these examples they both have just killed someone (in rage), but this reason didn't apply every time. There's also some speculation here: quora.com/Why-do-Sith-have-yellow-eyes

Eyes change color to yellow with deep immersion in Dark side, but exact mechanism is unknown

It is said that Dark Side represents destruction, corruption, will to power and egocentrism. Palpatine was almost perfect embodiment of these Dark Side ideals, so with his constant immersion in Dark Side, when not wearing his Chancellor mask, his face was disfigured and his eyes yellow.

On the other hand, his apprentice Dooku and assassin Ventress do not have yellow eyes. Dooku was never fully egocentric like Palpatine, he has his ideals about "Human empire" and that ultimately cost him his life. Also, Dooku tries to keep his gentlemanly demeanor even when he does some truly despicable acts. Ventress is a similar case, there is constant fight in her soul between good and evil, finally she chooses Light. It seems that both of these characters never fully embraced darkness, perhaps because their prior training as Jedi.

Anakin is most curious in this regard, his eyes constantly change color. Interestingly, when he does his most gruesome act - killing of younglings, his eyes are normally blue

enter image description here

but when left burning on Mustafar, his eyes are burning yellow. This could probably mean that he used all of his hatred and Dark Side power to help him survive (just like Maul did in similar circumstances), but he didn't need that to help him murder children .

enter image description here

Maul is another interesting example, his eyes are constantly yellow, even after his death in Kenobi's arms, when he supposedly let go off his hate. Note that Maul is actually only true student of Palpatine, raised by him since childhood unlike Dooku and Anakin who were once Jedi. Perhaps he picked up too much from his old master and could not shake it off even if he tried. I don't think his natural eye color was yellow, and reason is his brother Savage.

enter image description here

Savage Opress had yellow eyes while he was alive and enraged, but in his last moments they returned to natural green-blue color. This happened when Magick cast on him withdrew, implying that maybe his brother Maul had same or similar eye color before Palpatine got him as an apprentice.

Finally, we have Snoke. Although Disney really fumbled with this character, there are few things about him that lead to certain conclusions. Snoke is not a Sith, but he is very powerful with Dark Side, comparable to Palpatine (some say even more powerful) . Yet, his eyes are blue. Does this mean he is not fully immersed in darkness? Possibly, because he did mumble something about darkness rising and light to meet it, implying that Snoke believes in balance rather then just one side of the Force. Perhaps this is the reason he tries to connect Kylo and Rey? Anyway, this is all done very poorly, so we leave it at that.

enter image description here


The change of eye colours to yellow is caused by the dark side of the force. We know that Palpatine was able to use the force to conceal his "Presence". The effects of him temporarily "severing" himself from the force would probably also block the physical effects of the dark side from view.
