Chromatography, or, A treatise on colours and pigments : and of their powers in painting, &c.
George Field's 1835 London treatise on colours and pigments, issued by C. Tilt for painters, colourmen and students of optics. Engraved plates show wedge-shaped optical instruments in fine-line shading, a prism ray diagram labelled with colour names, and geometric colour-mixture schemes — sources for instrument silhouettes, hatched tonal surfaces and annotated light-path drawings.
