Answer:
The color orange wasn't actually called “orange” until after the orange fruit was officially named. They named the color after the fruit. When they were naming the fruit, red was already established.
Step-by-step explanation:
Because both words are variations of the original names for the respective fruit, from languages other than English. The color term “orange” comes from the name of the fruit, not the other way ’round, because our previous word was just “yellow-red”, and so it was liable to be replaced.
