Aristotle’s theory about colorThe theory of color developed by Aristotle is vital to the growth of many disciplines in science. In his book Colorology, Aristotle explores the connection between light and color. Among other things, he explains the origins of colors, methods for coloring, and the relationships between colors and objects.
Aristotle said that color was the reality of transparent matter. This means that the only way that a body can be colored is if it is illuminated. Aristotle stated that this is not required to make a person colored. He says that a human body will not be colored if it's located in a dark space.
One way to understand Aristotle's view is the fact that color is a force which reflects light towards the eye. It is not an untruth, as some seventeenth-century philosophers may think.

He studied rainbows and realized that when light enters prisms, it produces a rainbow. This rainbow is composed of many colors, which are then reflected back into white light.
He also wrote an entire book on the subject titled The Book of Colours. It was a summary of his theories on color.
