Abstract The simplest spectral‐power distributions of lights which match to a human observer intersect in three specific wavelength bands near 448, 537, and 612 nm. Simple lights which match to a detector intersect near the wavelength of peak spectral response of that detector. By analogy, the three specific wavelength bands must mark the peaks of spectral response of the normal human visual system. More complex spectral‐power distributions of matching lights may mask the relation between intersection behavior and visual system response.
