Color vision is the ability to distinguish different wavelengths of electromagnetic radiation. Color vision relies on a brain perception mechanism that treats light with different wavelengths as different visual stimuli (e.g., colors). Usual color insensitive photoreceptors (the rods in human eyes) only react to the presence or absence of light and do not distinguish between specific wavelengths.
We can argue that colors are not real—they are “synthesized” by our brain to distinguish light with different wavelengths. While rods give us the ability to detect the presence and intensity of light (and thus allow our brain to construct the picture of the world around us), specific detection of different wavelengths through independent channels gives our view of the world additional high resolution. For instance, red and green colors look like near identical shades of grey in black and white photos.
