Color
Color is the nature of the light determined by the wavelength. The wavelength visible for light is known as visible spectrum, or simply as a spectrum. The term color may also refer to the properties of objects or materials determined by the type of wavelength reflected, transmitted, or transmitted. Normally, only the light content that humans can detect is taken into account and therefore color can also be regarded as a psychological phenomenon. The processing of various uses of the term is the main task of the current philosophy. Because color perceptions come from cone cell sensitivity in different retina to different spectral parts, colors can be defined through the stimulation of the cells by the wavelength of light. Color physiology is discussed below. Color science is sometimes called chromatic and includes the perception of color by the eyes and the human brain, the color origin of the materials, the color theory of art, and the electromagnetic radiation physics in the visible range.
