A speculative theory of colour vision according to which the first photoreceptors to evolve yielded only achromatic (1) vision, receptors for blue and yellow evolved next, and receptors for red and green evolved most recently, the central area of the retina, where all colours are perceived, being the most evolutionarily advanced. [Named after the US psychologist and logician Christine Ladd-Franklin (1847–1930) who first published it in her book Colour and Colour Theories in 1929]
