1944 D. L. Fox in Science 100 470/2 From the standpoint of the biochemist..concerned with the metabolic significance of natural coloring matters, the designation of these by a discriminating scientific term has long been desirable. In response to an inquiry, Dr. George M. Calhoun..suggested to the writer [in a personal communication, 1936] the descriptive and self-explanatory term biochrome, with an adjective biochromatic (biochromic is perhaps preferable), and a collective noun biochromy.
1954 Sci. News 34 91 [Porphyrins] probably serve in this role, as well as a biochrome, in insects.
2005 Animal Behaviour 69 757/2 Psittacofulvins are the rare class of red, orange and yellow biochromes found only in the feathers of parrots.
