If Sonic the Hedgehog was specifically excluded from the dataset, DALL-E 2 has no way to know the hedgehog should be blue. Instead, I think it's interpreting "a portrait of Sonic the Hedgehog" as a hedgehog that happens to have a name, and almost all hedgehogs, regardless of their name, are the same color. Even if someone had added a blue realistic-looking hedgehog to the dataset, if they referenced Sonic their image would have been deny-listed. So the only way to get there is to add the adjectives one is looking for, such as `a portrait of a blue hedgehog wearing red sneakers and eating a chili dog`... And, indeed, when I try that prompt, I definitely get some Sonic-alikes.
