Trying to change the color of two items

I need help. I have two of the same spaceships on my scene, but when I go to change the color of the second one to look different from the first, it changes both of the spaceships colors at the same time… How can I change them to have two different colors?

Hi @Arieanna_Britt , are you using same material for both spaceships? Can you share you code or a sample project?
