Color is the visual perception that arises from the way our eyes and brain interpret different wavelengths of light within the electromagnetic spectrum. It is not an inherent property of objects themselves but depends on how objects absorb, reflect, or emit light

. Color perception in humans typically involves three types of cone cells in the retina, which are sensitive to different wavelengths corresponding roughly to red, green, and blue light. The brain processes signals from these cells to create the experience of color

. Colors have three main perceived properties:

• Hue : the basic color name such as red, blue, or yellow.
• Saturation (or intensity) : the purity or vividness of the color.
• Brightness (or value) : the lightness or darkness of the color

Colors can be mixed additively (combining light, e.g., on screens using RGB) or subtractively (combining pigments or dyes, e.g., in painting or printing using CMYK). Color spaces and models like RGB, CMYK, and HSL help quantify and reproduce colors consistently in technology and art

. In summary, color is the perception created by our visual system in response to light of different wavelengths, influenced by physical light properties and biological processing in the eye and brain
