Guy Coggins, the inventor of the biofeedback Aura Imaging, based his color interpretations on different electrical measurements. Each color has its’ corresponding electrical frequency that can be scientifically measured.
Coggins conducted extensive research on these measurements and was further inspired by the writing of Dr. Max Luscher who has been responsible for many renowned scientific studies on color preference and personality. He was most famous for his best selling book The Luscher Color Test . Dr. Luscher was a contemporary of Sigmund Freud and was very popular during the late 1960s. Guy developed the Winaura Imaging systen that we use now.
