The Earth's resources?

Question

When we talk about resources, we usually think about oil, but im wondering about everything else. For example, how about the color yellow? It comes from somewhere? Sure we can reproduce it in labs by mixing this and that, but when does "that" run out? Are there huge mining quarries where "yellow" will never run out?

Answer 1

yellow is a color not a resource....a resource is something that is used ofr some kind of purpose....yellow is simply a wavelength.....when light hits an object it reflects certain wavelengths back and absorbs others....something that is yellow is absorbing all but the yellow wavelengths which are being reflected back....therefore it is not a resource just like red and blue are not.
