The Paul Goldin Clinic in Dublin Ireland developed Colorgenics which is a culmination of many years of clinical research. The Colorgenics Profiler analyzes your choices of color preference and reveals to you your underlying character traits and provides insight into your physical well-being.
The clinic is also looking into Colormonics. Initial research indicates that by visualising specific colors at the same time as listening to harmonics of subliminal sound frequencies, an individual’s subconscious mind may be activated and this can result in the development of ones inherent psychic powers and the ability to break specific bad habits, like smoking.
My Colorgenics profile begins with: Much of the time you are preoccupied with things of an intensely exciting nature. Who me???
UPDATE - It looks like the Paul Goldin Clinic is no longer in operation. Check out some of these personality tests I found on AllWomansTalk.
