wait…is Terezi really blue blooded? So my theory on blood ranking being blue = top means that Karkat has a lot of high class friends.

But if Terezi doesn’t know…does Karkat high his blood status so that his friends won’t treat him differently? Is that why his icon text is grey? Not because he has grey blood, but because he doesn’t want to show himself?

This sort of explains his inferiority complex if that’s true
