Sometimes when we talk about someone we might say something like "she has a colour" or "she has an age". But we do not say "She is age" or "She is colour", so, where do the terms "Colour" and "Age" (and other terms like that) fit into Aristotle's works?

Additionaly we say things like "she is 60 years old" when we know that her age is 60 years. So there must be a connection somewhere between the predicated "is 60 years old" and "age" i just can't see where?
