If a photoelectric cell instead of the eye is used to compare intensities, the instrument is called a photoelectric colorimeter. In colorimetry, frequently the entire visible spectrum (white light) is used, and consequently the complementary colour of the one absorbed is observed as transmitted light. If monochromatic light or a narrow band of radiation is used, the instrument is called a spectrophotometer.
