After discovering that coloration was a good index for assessing the quality of his beer, he sought an accurate method of measuring color. He developed an apparatus, which he called a "tintometer" and later manufactured and marketed as a Lovibond Comparator.
This work details the results from twenty-five years of experimentation while perfecting his tintometer, the instrument that would provide a reliable judgment between two colors that are "very nearly but not quite alike." In reference to the scientific nature of the work, Lovibond states "although some of the phenomena dealt with may have a bearing on the physical laws of light, the main question is psychological, that is to say, dealing with the power of the vision to appreciate, rather than with the definition of the laws themselves."
The work includes several charts and illustrations as well as thirteen colored plates. The work is digitized in its entirety.
