  • If a nomenclature of this kind be admitted..the whole class of processes in which cyanogen in its combinations with iron performs a leading part, and in which the resulting pictures are blue, may be designated by this epithet. The varieties of cyanotype processes seem to be innumerate.

    —Herschel, 1842, quoted in OED

    Late Sunday afternoons, we climbed from the lake bottom, covered with prehistoric ooze, to surface under a billboard on St. Clair Avenue; the tram tracks shining dully under the weak winter sun, or stropped bright under the streetlights, the evening sky purple with cold or cyanotype summer blue, the darkening shapes of the houses against the dissolving bromide of twilight.

    —Anne Michaels, Fugitive Pieces, 1997
