The colors that we see are a result of the absorption and reflection of various wavelengths of light, and our eyes and brain are designed to receive these wavelengths as different colors. The white color that we see is a combination of all possible wavelengths of light.

• The perception of color greatly depends on the spectral sensitivity of cells in the retina to different colors. The colors we see are defined based on the degree the retina's cells are stimulated, therefore making colors actually a physiological phenomena.
• Chromatics is the study of color, which seeks to understand the way color perception works in our eyes and in our brains. The color of any object we see will depend on the environmental physics the object is placed in, as well as the characteristics of the Seeing Eye and the brain. This is why some people do not perceive color the same way; for one person a color may be lavender while for another it may be purple.
• There are three kinds of color receptor cells in the human retina, which makes us trichromatic. One type of cell is the most responsive to light that we see as violet, these types of cell cones are called short-wavelength cones. The other two kinds are more closely related than the first based on the chemical and genetic makeup. The second can be referred to as long-wavelength cones which are more sensitive to the light that we interpret as yellow green. The third and last is the middle wavelength cone which is more sensitive to lights that we interpret as green.
• While the perception of color in the eye is described above, the process that registers it in our brain is entirely different.

The study of color and light is a very interesting discussion. It is a complex yet very interesting biological feature.
