T-Rex: My favourite colour? Oh, you wouldn't have heard of it.

T-Rex: It's CHIMERICAL.

T-Rex: That's right, babies! We have cone cells in our eyes that help us see colours, but if you stare at one colour long enough, those cells get PLUM TUCKERED OUT. Then when you look at a DIFFERENT colour, your eyes detect it as a shade NOT NORMALLY VISIBLE! You have seen an IMPOSSIBLE COLOUR.

Utahraptor: So what IS your favourite colour?
T-Rex: Today? HYPERBOLIC ORANGE.

T-Rex: Stare at bright cyan to produce an orange afterimage in your eyes, then stare at orange to see a shade of orange more orange than any orange orange that ever oranged! And while you do so, whisper "oh wow, T-Rex was right!"
Utahraptor: Does it work if you don't whisper?

T-Rex: Nope!
God: EDITOR'S NOTE: ACTUALLY YES
T-Rex: Oh wow God, THIS is what causes you to start editing reality??
