Chromatotherapy uses energies determined by their wavelengths. It also induces an answer from the body, answer which is also an energy. This energy therapy has thus as preferred field of action the pathologies provoked by the surrounding energies. 
A burn is an aggression caused by a heat energy , a chilblain by a cold energy, a trauma by a cold energy etc…

To a burn, which is an excess of heat energy, it is better to answer by an other energy (in this case, a cold one) rather than by a molecule, even a very efficient one. To a pathogen energy, it is better to answer by an opposite energy before the appearance of physical damages.
The sooner the energy treatment the more efficient it will be. It can prevent the appearance of anatomical lesions.
