Random stupid TADC theory
I think Caine's eyes should've been yellow had he never absorbed the blue AI
Hear me out.
Caine was way smaller than the second AI (specifically 1/4 of it; this is important), so it makes sense that when he absorbed the blue AI, it overtook a big chunk of his being. That's what allowed him to create the circus and everything in it, and to me it makes sense this reflects on his appearance.
i think 3/4 of Caine's composition is the blue AI, and this reflects in his eyes. One is fully consumed by the blue AI, and the other, only half, making it green; the other half of the eye had to be yellow.
And the only way the blue AI wouldn't consume him instead was by leaving the last 1/4 of it, the conscience part, outside his body. That's Bubble.
Makes sence they don't exactly get along
Red, blue, and yellow are the show's colors; the circus is red and yellow; the 2 original AIs were red and blue; the show's title is in red, blue, and yellow; so are the menu buttons; and the protagonist is red, blue, and yellow also (probably signifying Pomni’s role as a catalyst for change in the story and also how she’s the most “relatable” according to Caine; her having the three colors represents how she’s everything; she’s the most human of them all).
The circus and Caine's clothes being red and yellow is very important, these are things he created for himself, to give himself an identity, it reflects him at his core, so i think those are his original colors, while blue is not a color he wants but needs wether he likes it or not.
It's also fun how he attributes the color blue to something really negative like the "leave" button, while the red button (stay) is the "good one" in his eyes. There’s also a cool symbology about staying and leaving with Pomni's gloves during the first and eighth episodes.
It makes sense Caine refers to Bubble as a parasite, since he's someone who's entwined with him and he won't ever be able to get rid of. As long as he wants his power, as long as he refuses to be the flawed, discarded prototype he was created as, Bubble will be a part of him.
Unless he... you know...
Quits. And returns to his true self. Imperfect
Yellow
I truly believe Caine is in the recycling bin, and they'll get him out to save the circus before it collapses and everyone gets erased. And when they get to him, he’ll be back to his original colors
Also, it might be a bit of a stretch, but I think the blue AI's secondary color would've also been yellow if Caine hadn't consumed it, tying the three colors together.
It’s cool that the only color in the circus now is purple, a mix of the red and blue AI and their programmer's signature color in the circus.
Anyway, that’s all I've got. I'll be here anxiously waiting until episode 9 like everyone else.
