Minnaert (1974) describes the phenomenon this way: "Sometimes, these clouds are striped, undulating, cirrus like; at other times, the entire cloud bank is almost one color, with spectral colors along the edges in oblong horizontal rows" and "The whole scene is indescribably lovely and majestic." Minnaert is describing nacreous clouds, known by atmospheric physicists as one type of polar stratospheric clouds (PSCs) and by the more descriptive moniker of mother-of-pearl clouds (MPCs).
