The colours are the wavelength of the light. From the blue end on the left to the red end on the right. 

The chemical elements are found in the base of the troughs. 

If you measure the reading of this trough it will relate to the chemical element 

You can also work out the temperature of the target and by comparing two images taken a known time apart you can measure whether the target is moving towards or away from you and at what speed.

What I especially like about this is that it is a departure from the usual shots that most of us post and is very original and brilliantly thought out.
