What is defined as the distribution of colors produced when light is dispersed by a prism?

The distribution of colors produced when light is dispersed by a prism is referred to as the color spectrum. When white light passes through a prism, it separates into various colors, which are typically represented as red, orange, yellow, green, blue, indigo, and violet. This phenomenon occurs due to the refraction of light at different angles based on its wavelength, resulting in a continuous gradient of colors. The color spectrum is fundamental in both art and science, as it illustrates how various wavelengths correspond to different colors, and it aids in understanding color mixing and perception.

In contrast, a color wheel is a visual representation of colors arranged to show their relationships, a color palette refers to the specific set of colors an artist chooses to use for a particular work, and color theory encompasses the principles and guidelines that govern the use of color in art and design. These definitions help clarify the distinctions among the terms, underscoring why the color spectrum specifically pertains to the phenomenon of light dispersion by a prism.
