Well, IIRC it is assumed most if not all Dinosaurs have good tri or tetra colour vision, similar to Birds.

But then again, Cassowaries are mostly opportunistic small prey predators/scavengers that generally live in nigh impenetrable rainforest, not at all comparable to Ceratosaurus AFAIK

All of them ? Including things like Stegosaurs and sauropods ?

I think so, and its easy for both of those groups can use Colour for communication and display, Stego's plates and sauropods freedom of flamboyance.

Given the following:

1) Most modern reptiles including/and birds have exceptional colour vision.
2) Many dinosaur clades relied on crests, frills, tail fans, wings, throat flaps, wattles, and bright coloured integument for communication.
3) Their relatives, the pterosaurs, relied extensively on elaborate, to the point of ridiculous, head crests for communication.

It's likely that colour vision was a basal trait among sauropsids as a whole.

As for TETRAvision, that's a bit more complicated because I don't think it's known outside of birds, and even then, it's my understanding that it only occurs in some clades, not all modern birds. I'll need to look this up to be sure though. I wouldn't rule out some dinosaurs having that condition, but I wouldn't generalise it.

Wouldn't be a disadvantage if the animal wanted to hunt? :P I mean such bright colourations will make it easy to spot in the distant by its preys. Except of course, if those colors were present only during mating season.

Anyway, i really love both the Ceratosaurus and the Dilophosaurus reconstructions. Who is the artist?
Well, I think I have heard somewhere that Ceratosaurus is probably a nocturnal predator... So, if that's real... Blue horns are not actually a problem for the predator.

I am on phone now, so I am gonna post the DA page of that artist later.

It's a mutation called tetrachromia. While the cells in their eyes can detect UV light and forward it to their brains, Hhuman brains aren't actually built to handle it. People with tetrachromia end up with seriously bad migraines quite often because it's like constantly staring into the sun for them.

Also, what evidence do we have that Ceratosaurus was nocturnal?

But going back on topic, another favourite dino reconstruction of mine is not one that I could technically SHOW you right now, but it's definitely, by far, without a doubt my favourite T. rex reconstruction ever.

Kind of an... on going project... Yeah, that... B-)

Do you have any non shrink-wrapped reconstructions? :P

Just kidding, indeed Parasaurolophus is awesome. Though there is absolutely no evidence at all that it could paralyze predators with its calls (I don't even see how that would work TBH), and BTW it never lived alongside T. rex either (though it was potentially preyed upon by related tyrannosaurids such as Gorgosaurus).
