How does reflected light determine the color seen on an object?

In the context of interior design and architecture, color is defined as the quality of light reflected from an object to the human eye. When light falls upon an object, a portion of that light is absorbed by the material, while the remainder is reflected. The specific color perceived by an observer depends directly on the wavelength of the light that the object reflects.1

Because different light sources possess varying spectral energy distributions, the same object may reflect different energy distributions depending on the illumination. Consequently, the apparent color of an object is not an inherent, static property but is contingent upon both the light source and the object's physical interaction with that light. Designers must account for these interactions, as well as the influence of surface textures, which significantly affect how light is absorbed or reflected within a space.21
