Abstract

THE trichromics, that is those who see three colours in a bright spectrum, red, green and violet, are confused by many with the anomalous trichromatics, whereas they are quite distinct. The anomalous trichromatics, as defined by the late Lord Rayleigh, make an anomalous equation and do not agree with the normal equation, and they may not be colourblind. The trichromics are invariably dangerously colour-blind, and though they may make an anomalous equation they may also agree with the normal equation.
