Why are things colored? Scholars have learned that all the colors in the universe originate from a mere fifteen fundamental physical causes, all of which are summarized in five groups in this exhibit. You can read about the way light is generated by objects such as light-bulbs or fire. Light can also be lost or absorbed by objects or it can interact with the environment and be modified to produce color, without itself modifying the environment, as happens for example in a rainbow. It is also interesting to read about other issues related to color, such as colorblindness, color vision of animals, and aspects of color theory and the mind.
