Is this true?

gameObject.GetComponent().material.color

  1. color is a class of material.
  2. material is a class of Renderer.

Also, if you could tell me what a class is, I would appreciate it!
Thanks in advance.

I don’t mean to be rude but I’m sick of people trying to use Unity without bothering to even look at learning C# or UnityScript first.

With that out of the way:

Color does not inherit from material.

Material does not inherit from Renderer.

Color is a struct and not a class.

Structs for beginners - C#

Classes for beginners - C#

I’d advise watching both of those tutorials series from start to finish before you continue to use Unity.
