I Don't Know What They Look Like, Right?

The best analogy probably for the non-avian dinosaurs is the avian dinosaurs, the birds. We don't know what they look like so why make this consistent set of assumptions that they were brown and gray? It's just as valid to think of them as orange and pink. But we could think inferentially about what color they might have been. And again, it's definitely reasonable to think of birds when you're talking about the feathered dinosaurs.
