Chromotherapy: Color in Ancient Times
Healing through color, or chromotherapy, has been practiced since ancient times. In Egypt, Iran, India and China, people knew of the healing properties of color and applied them in many ways. The rooms of the Heliopolis temple were designed in such a way that sunrays separated into the seven colors of the spectrum and were used in healing. In the mosques of Iran, multicolored glazed tiles were used for inspiration and purification of the spirit. 
These cultures used color in different ways in architecture, water, light shining through crystals and the consumption of gems ground into a powder. 

Chromotherapy: Dynamic Balance
Nature is based on dynamic balance, whatever the form in which it is expressed; a fern opening its dense spiral to the sun, a nautilus resting at the water’s edge, and a sunflower standing tall and radiant express the same proportional relation in nature. That “aura” relation can be found in the human body, in plants and in animals. 
What we see in the visible part of the spectrum is the part of the electromagnetic spectrum that contains energy, from cosmic rays to radio waves. Sunlight, or light from the complete spectrum, contains all the wavelengths of color, from ultraviolet to the visible spectrum, including infrared.
The effect of sunlight during the winter is a demonstration of the role that color plays on our health.

Chromotherapy: the Human Aura
The aura is the layers of color that surround the human body. The set of these layers forms the auric field. When we feel healthy, the eight colors of the field are light and luminous. If the body is out of balance, some concrete colors may appear darker or pale, less substantial. We can experience the quality of auric color through the trick of a mental persistence of an image after looking at an object, something that our eyes do well. 
Fix your gaze on a bright turquoise object or square of paper and look at it intensely for three or four minutes. Then immediately divert your gaze toward a nearby sheet of white paper. Instantly you will see a red square softly glowing on the white paper. That glow is similar to the quality of auric color. 

Chromotherapy: The Color of Our Daily Lives
How can we take this marvelous energy that is part of our daily experience and take advantage of it to enrich our lives and to heal some affliction? The first thing we must remember is that nature loves balance, which is why the complementary principle is often applied in healing. If one color is used, its complementary color is also used. A healthy body contains complementary colors in equal proportions. 

Chromotherapy: Meditation with Color
Remember one of your favorite places in nature, a place where you can relax and feel safe as if you were home. Lie down, get comfortable and start breathing naturally and softly. In your mind, go to that place. Remember a time when you felt happy and relaxed there. If a place and a specific moment don’t occur to you easily, imagine a story about a place in which you would feel happy and relaxed. Imagine going there, lying down comfortably on the ground or sitting tranquilly in an armchair. See the colors around you. Breathe them in with all their richness as you see them with your mind’s eye (the third eye). See the bright blue sky, the blue lake in the distance, the green grass surrounding you, and the orange, reddish, yellow and violet flowers in the gardens around you. Breathe in the colors. Mentally intensify their richness and variety. Remain there for ten minutes. Then gently return to the present, invigorated and relaxed. As you practice this exercise, you will become better able to introduce more detail and variety in the color. 

Chromotherapy: Visit a Color Therapist
In health-related professions, the importance of emotions is now acknowledged, since they affect our state of health. Being aware of our feelings is not always as easy as it seems, especially in today’s fast-paced world. 
A good professional will listen to you attentively, see you with an open mind and heart and, using the diagnostic tools currently available, suggest a treatment to free you of blocking so that your body’s energy can recover its dynamic balance. 
In chromotherapy, a series of measures are used for diagnosis and treatment. Some professionals read the auric field in order to diagnose the state of balance of color in the body. Others make a reading of the balance of the energy of color in the spine and then, with the use of a graph, establish a program to put the color energy in balance, if necessary. 
Psychological tests in which color is involved can be used. The Luscher test, for example, uses the conscious mind of a client as well as the unconscious mind, in order to obtain physiological information. In art therapy, paints are used to see how a patient expresses his/her attitude toward life at any given time. 
Colored light is the most subtle, efficient way of using color in healing. These treatments should only be performed by trained professionals with ample experience in the use of color. 
Water, in bottles covered with filters for the different colors of the spectrum, and colored oils obtained from natural vegetable materials, permit one to work at home in order to assist the healing process between sessions. The colors used in your home, clothes and food will also be highly useful, as well as the use of colored silk garments. 
Currently, chromotherapy is used in complementary medicine to treat spiritual, mental, emotional and physical ailments. The key is recovering the balance of the body, in which color is a very good tool. 
Chromotherapy is complemented with acupuncture, acupressure, work with essences and herbs, and visualization. What we must always remember is that color is a festive aspect of our world and also of ourselves. 

Chromotherapy and the Chakras
Many traditions recognize the existence of seven chakras. Chakras are energy centers that are found in line with the spine, right on the outside of the physical body. Each chakra has a color and a specific effect.
