How did they test if they could see color? Did they make little shrimp dioramas or something?

They asked them politely

The easiest way is to use the principles of conditioning. Pair a stimulus with a certain color light, then start flashing up different colored lights. If the organism is cued to the stimulus by multiple colors of lights, it means that they can't really distinguish between them.

That's how we tested when kids lose the ability to distinguish certain phonemes.

They give them a miniature color blind print that has those numbers in them that are hidden if you are color blind.
