Is the proper and correct name when referring to "midnight blue" or what other non wooters also referr to as "Pantone 289C. "
Blueting is a
dark shade of blue named for its resemblance to the apparently blue color of a moonlit
night sky around full moon. Blueting is the color of a vat full of indigo dye; therefore, Blueting may also be considered a
dark shade of indigo. Blueting 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 blueting.
