Various wavelengths are compared with complementary combinations of pairs of short and long wavelengths to determine their relative efficiencies for neutralizing unit power of the complementary color. For 14 whites defined by Planckian sources from 2000 K to infinite K color temperature and beyond, single wavelengths shorter or longer than a "primary-waveband" (e.g., 437.5–614 nm, for D₆₅ white) are less efficient than combinations of short and long wavelengths. The "primary-waveband" varies according to the color temperature of the white. Equations are given to find "primary-waveband" intervals and limits in all whites from 2000 K to infinite K color temperature.
