The laws of contrast of colour

A scientific and practical examination of colour contrast begins by defining simultaneous contrast and demonstrating it through systematic experiments and a representative formula, distinguishing simultaneous, successive, and mixed effects. It analyzes how colours alter one another when set beside white, black, grey, or related hues, presents chromatic diagrams, tones, scales, and rules of harmony, and offers detailed applications across painting, tapestry, dyeing, printing, dress, military clothing, illumination, and gardening. Practical rules for mixture and weaving — binary primary mixing, complementary mixtures, and three-colour combinations — accompany illustrative plates and guidance for achieving consistent colour relationships in decorative and pictorial work.
