Color is the impression produced by a tone of light on the visual organs, or more exactly, it is a visual perception that is generated in the brain of humans and other animals by interpreting the nerve signals sent by the photoreceptors in the retina of the eye, which in turn interpret and distinguish the different wavelengths that they capture from the visible part of the electromagnetic spectrum. The whole illuminated body absorbs a part of the electromagnetic waves and reflects the rest. The reflected waves are captured by the eye and interpreted in the brain as different colors according to the corresponding wavelengths.
