During his early cameo, debut, and filler appearances in the Dragon Ball Z anime, Vegeta originally appeared with a totally different color scheme from his usual one, being depicted with reddish-brown hair, a light green and orange armor with guard plates, a navy-blue jumpsuit, orange gloves and dark brown boots with orange uppers. His new form gave him blue eyes with a black pupil. If memory serves, through all of DBZ, GT, and super, all saiyan eyes were solid colors (aside from Goku in ultra instinct only).
They even showed Goku's eyes afterwards and they were a solid color. Is it just specific of this super Vegeta blue form? The original color is supposed to be red. There are instances when their eyes are colored green, yellow etc.
It comes down to design. Just like Goku and Vegeta appear a lot skinnier now. Also, Vegeta seems to be taller in comparison to Goku than he was before.
All these vary based on the staff for the particular series/ episode. This isn't reddit. Questions and answers are supposed to be.
Ssj4 Vegeta has Blue eyes and Goku yellow. I thought ssj forms had a uniform eye colour. Ssj 1-3&R.
Why do Super Saiyan 4 Goku and Vegeta have different Eye Colors?! Vegeta's features are quite different from his previous forms. His hair style changes, becoming longer and more wild. His hair becomes dark brown, and extends to his shoulders, his eyes are aqua-colored, and he has red fur on the upper part of his body.
The Most Commonly Seen Eye Color: Green You've probably noticed that the most commonly seen eye color for Super Saiyan characters is a bright green! These piercing, emerald eyes are often seen in iconic Super Saiyan moments, like when Goku goes Super Saiyan for the first time against Frieza. For me I feel like Super Saiyan 3 is the weird outlier. Super Saiyan and its variants don't have pupils because it looks more intimidating, and it doesn't matter what your original eye colour is for that.
Super Saiyan God (despite the name) and Ultra Instinct don't have anything to do with Super Saiyan, so the eye colour change keeps the pupils. Muscle mass, hair color, eye color, aura, etc. But for some reason in SSJ4 Goku and Vegeta look 99% the same except their eye color.
My theory is that because Goku reached this form naturally his gold/yellow eyes are what they should be. Since Vegeta reached it synthetically, that is the reason Vegeta has green/blue eyes. Im guessing this is the scene dodoria was telling vegeta about how frieza blew up his home planet and it wasn't a meteor.
Vegeta already knew but is obviously still sad about it all, so in traditional anime style they blur out the eyes to hide expression.
