This lecture was aimed to highlight the importance of colors in our daily life and to introduce colors and how to mix them to obtain multiple colors as they affect vital activities, like features, follow the changes of the emotions, color can dramatically affect moods, feelings, and emotions Color is a powerful communication tool and can be used to signal action, influence mood, and even influence physiological reactions. Certain colors have been associated with increased blood pressure, increased metabolism, and eyestrain.
The lecture included the physiology of color vision in human and animals , and how it occurs and who is responsible for it. In humans, the perception and ability to distinguish different colors is mediated by a variety of mechanisms in the retina as well as the brain. Understanding the physiologic basis of color vision is essential to detecting abnormalities and devising treatments.
Most mammalian retinae only contain two types of cones (dichromats), sensitive to short wavelengths (S cones, maximally sensitive near the blue end of the visual spectrum), and medium wavelengths (M cones, maximally sensitive to green wavelength light).
Humans, as trichromats, have an additional L cone, which is sensitive to long-wavelength light at the red end of the visual spectrum. Each type of cone is associated with a different opsin, which has different genetic bases. S cone opsins are autosomally encoded on chromosome 7, while M and L cone opsins are located nearby on the X-chromosome and are nearly identical. M and L cone opsin genes are believed to undergo frequent homologous recombination, which underlies changes in normal spectral sensitivity that explain the variations in the severity of red-green color blindness. These defects are far more likely to affect karyotypic males than females as they are sex-linked. S cone opsin defects are far less common than M and L.
Several ancient cultures, including the Egyptians and Chinese, practiced chromotherapy, or the use of colors to heal.
Chromotherapy is sometimes referred to as light therapy or colorology.
Colorology is still used today as a holistic or alternative treatment.2 In this treatment:
Red is used to stimulate the body and mind and to increase circulation.
Yellow is thought to stimulate the nerves and purify the body.
Orange is used to heal the lungs and to increase energy levels.
Blue is believed to soothe illnesses and treat pain.
Indigo shades are thought to alleviate skin problems
