Chrome Zen Therapy is a color-based natural healing technique that uses colors to help people. 

What makes it different from other healing techniques?

It uses the science of colors, a natural healing agent that has been known to work for many years. It can be applied to the whole body or to a specific area. The user can specify the duration of each of the therapies and have access to a track to see its progression in every color.

In addition, the user has access to a list of all the colors and can select the one he wants to use.
