Color fundamentals

From the journal Physical Sciences Reviews


Colors are only created in the human brain. During this process, light rays from the environment reach the retina of the eye. There they trigger an optical stimulus, which is transmitted to the brain. And the brain translates this stimulus into colors. The perception of color is influenced by multiple factors, which is why it is highly subjective.

Originally, the light rays come from the sun. They are described by the color spectrum, which comprises rays visible to us from 400 to 700 nm. These light rays can be influenced by different pigments that manipulate the light rays. This manipulation can happen by absorption, reflection and refraction and interference.
