If you’ve ever seen A Mighty Wind you’ll rememeber a scene where a married couple of has-been folk singers talk to the interviewer about their spiritual beliefs. This should help refresh:

Terry and I worship an unconventional deity. The power of another dimension. Now you are not going to read about this dimension in a book or a magazine because it exists nowhere… but in my own mind. Through our ceremonies and rituals we have witnessed the awesome and vibratory power… of color.
We are Winc. W-I-N-C. Witches In Nature’s Colors.
This is not an occult science. This is not one of those crazy systems of divination and astrology. That stuff’s hooey, and you’ve got to have a screw loose to go in for that sort of thing. Our beliefs are fairly commonplace and simple to understand. Humankind is simply materialized color operating on the 49th vibration. You would make that conclusion walking down the street or going to the store.

It’s one of my favorite scenes if for nothing else, the look on the husband’s face of deferential resignation to his headstrong and deranged wife. Anyway, I thought they made up the religion for the movie, but there are actually people that claim to subscribe to it.
This site is awesome. It’s these two crazies that have a New Age business that sells books, does readings, consultations. Here’s a bit about colorology:

There are a number of simple, inexpensive and effective ways to intentionally employ color:

Visualization — Simply imagine a ray of light of the desired color penetrating and bathing the dis-eased area. Researchers have found that thoughts have a tangible effect on the physical body, measurable by EEG machines and other methods.

Solarized water — Place a clear, glass bottle filled with distilled or purified water and covered with colored cellophane in direct morning sunlight for approximately two hours (a transparent colored glass bottle may also be used). The vibratory frequency of the water will change to that of the color through which the sunlight is filtered. The water can then be consumed internally (sip gradually throughout the day — don’t gulp it down!) or used as a compress. Do not allow the bottle to come in contact with metal (use a corked bottle), and do not refrigerate it.

No, definitely don’t refrigerate it.
If you have time, explore the site. There’s lots of great stuff including: sweet illustrations, and therapy for children who have had contact with aliens.
