!!How Typical Cartoon Animal Colors Affects Perceptions of Animal Colorations
Often times animals in fiction have palettes that look realistic or natural but aren't actually. While the colours aren't too abnormal (such as a pink gorilla or purple giraffe), for the species or breed it's actually impossible if not very unrealistic. For example, genetically solid orange and cream cats in real life show at least a few tabby markings or stripes, but cartoon ones appear one solid color. This rarely if ever appears in live action for obvious reasons. Several of these are due to TypicalCartoonAnimalColors. Over time the trope becomes so commonplace that people are surprised that animals aren't like they are in fiction, such as how real gorillas aren't brown (they're black with dark grey faces, chests, bellies, hands, and feet) and how real alligators aren't green (they're blue-black or dark grey with off-white underside and belly scales).
!!All Birds' Beaks Are Yellow Assumption
One example of pop culture and fictional media infusing people's knowledge of he real world is the fact that most fictional and cartoon birds' beaks are yellow or yellow-orange. This has led to the assumption that all birds' bills are yellow. This assumption gets so commonplace that people are surprised to find out that some birds' beaks aren't like they are in fiction, like how real crows' and ravens' beaks aren't yellow (they're black or dark grey) and neither real cardinals' beaks (they're red).
