The space-threshold of colours and its dependence upon contrast [microform] : first article

Lane, Wilmot B. (Wilmot Burkemar), b. 1871, Baird, John Wallace, 1869-1919, Richardson, R. J. (Robert John), Kirschmann, A. (August), 1860-1932 · 1898 · [Toronto : s.n. · 11 pictures

A 1898 scientific article on colour perception by Wilmot B. Lane, John Wallace Baird, R. J. Richardson and A. Kirschmann, issued in Toronto for a psychological and physiological readership, and preserved here as a microform copy. Its figures are spectrum strips, a line graph of measured values, and a microfilm test chart rather than decorative illustration, so a designer would take from them only the look of early experimental diagrams: stark tonal gradients, labelled colour bands, and thin dash-dot plotted lines.
