Color is a visual perception resulting from the interaction of electromagnetic radiation with matter. Scientifically, color relates to the wavelengths within the visible spectrum, typically ranging from approximately 380 to 750 nanometers. When visible light encounters an object, the object either absorbs certain wavelengths and reflects others; the reflected wavelengths are what the brain interprets as the object's color. This process involves physical optics and biological mechanisms, specifically photoreceptors in the eye that transduce these wavelengths into electrical signals. The interpretation of color requires the complex processing of these signals in the visual cortex, allowing the brain to assign perceptual meaning to the received spectrum.
