This is an accepted version of this page Midnight blue is a dark shade of blue named for its resemblance to the apparently blue color of a moonlit night sky around a full moon.
Midnight blue is identifiably blue to the eye in sunlight or full-spectrum light, but can appear black under certain more limited spectra sometimes found in artificial lighting (especially early 20th-century incandescent).
It is similar to navy, which is also a dark blue.
The first recorded use of midnight as a color name in English was in 1915.
Midnight blue became an official crayola color in 1958; before that, since having been formulated by Crayola in 1903, it was called Prussian blue.
