This section explores how visible light interacts with objects, determining their colors. It explains the different outcomes when light strikes an object—whether it is reflected, transmitted, or absorbed. The color of an opaque object is defined by the light it reflects. It also highlights the distinction between combining colors of light, which results in white, and mixing pigments, which yields black. For additional insights, a video on color is available for further exploration of these concepts.
