Colour-blindness and colour-perception [electronic resource]
Colour-blindness and colour-perception is an 1891 London treatise on colour vision by ophthalmologist Frederick William Edridge-Green, published by Kegan Paul, Trench, Trübner and held at University College London. The four pictures are a pair of colour-matching still lifes of a jar, cup, bowl and fruit, a psychophysical colour-perception bar chart, and a medieval-style drawing of a kneeling figure labelled 'Domine ut videam'; a designer might borrow the flat, muted colour blocks of the still lifes and the simple bar diagram's palette.
