I try to give different base colours to my objects but when I define a base colour for one object, a couple of objects get the same colour at the same time. made a new material for those ones to separate their material from each other but when I add the base colour to those it's not showing it. then I went to every object and pressed P to separate them from each other but it didn't help. I also unwrapped the object just to see if it helps. but it didn't.
Can you help me figure out what is the problem?
