hordak headcanon idea thingy
hordak is tritanopia colourblind, meaning he can only see reds and cyans (correct me if i’m wrong!) which means he can slightly see purple too. the colourblindness is part of his defect/illness which is why his eyes are red. i think that they turned red as his illness worsened and/or were damaged in battle, either way they changed after prime sent him to the front lines, though they could have turned red before and prime had believed he had fixed them. i don’t believe the colour of his eyes and teeth are connected as in the scene with horde prime when his eyes are returned to their natural green hue his teeth are not, i have no headcanon on why his teeth are the colour they are, nor do i know if it has been confirmed if they are connected and why his eyes and teeth are red.
