Colour Measurement and Mixture

A thorough exploration of how light, pigment and perception intertwine, this work guides listeners through the practical side of colour science. Beginning with the basics of sources, spectra and the construction of a colour‑patch apparatus, it shows how to measure the intensity and luminosity of individual hues, even for those with colour‑blind vision. Detailed illustrations accompany explanations of absorption, scattering and the invisible parts of the spectrum, making the physics tangible without delving into historical debates.

The second part moves from measurement to manipulation, describing how simple and compound colours combine, how complementary pairs are matched, and how numerical equations translate visual impressions into precise values. Readers also encounter discussions of after‑images, eye fatigue and the use of coloured discs to test perception. Throughout, the author’s experimental methods—originally devised for lectures at the Society of Arts—remain the thread that ties theory to hands‑on observation, offering a clear window into nineteenth‑century colour research.
