Metals are colored because the absorption and re-emission of light are dependent on wavelength. Gold and copper have low reflectivity at short wavelengths, and yellow and red are prefeentially reflected.
Here, when all frequencies of visible light focus on a gold, short wavelengths light does not re-emission. Then, the short wavelengths are absorbed as heat inside gold???
 

Mentioning gold sounds like you've been reading some of Kanzius' work.

Think about it this way: on a sunny day, what color gets the hottest? Why is that?

It's not just about metal. Any material works on the same principles of light absorbtion and reflection. If it appears darker to your eyes, it's because it's absorbing more light.
 

My question is that where does absorbed light inside material?? They become a heat??
