monochromatismn.

Brit.

/ˌmɒnə(ʊ)ˈkrəʊmətɪz(ə)m/, U.S.

/ˌmɑnəˈkroʊməˌtɪz(ə)m/

Origin: Formed within English, by compounding. Etymons: mono- comb. form, chromatism n.

Etymology: < mono- comb. form + chromatism n., after monochromatic adj. Compare earlier monochromatist n., and also dichromatism n.

1. Physics and Zoology. The quality or fact of being monochromatic; monochromaticity.

c1865 J. Wylde Circle of Sci. I. 54/1 We now proceed to investigate a series of..phenomena connected with mono-chromatism... Under certain circumstances..a variety of interesting phenomena is presented when light of a single colour is used.

1974 Solid State Communic. 15 1249 Monochromatism of emission in each line is Δν/ν ≤ 2×10⁻⁶.

1999 Amer. Naturalist 154 182 The fact that estrogen-dependent dichromatism is ancestral in extant birds suggests that more brightly colored monochromatism may have been ancestral in modern lineages of birds.

2. Ophthalmology. Complete colour-blindness; the condition of being monochromatic (monochromatic adj. 3).
