gave me a piece of Titanium and showed me how to use it.
If you heat up Titanium, it changes colors from brownish to purple and blue. The color is made by interference of light. The light rays are refracted and diffracted by the different layers of the pure metal and the layers of the heat-generated oxides. These layers work similar to a grid that diffracts light. The interference deletes some wave lengths (colors), while others get amplified.

It is the same principle you see when you throw two stones into a water.
