Why is copper and gold differently colored than other metals, while all the other metals are close in color?
I was wondering, why is copper and gold differently colored than other metals, while all the other metals are close in color?
Copper and gold are more colorful because they absorb certain wavelengths of light and reflect others. The electromagnetic radiation that we see as visible light is actually a form of energy, and when it interacts with copper or gold atoms, it causes the electrons to move to higher energy levels. This results in the unique colors we see.
