Acid Mira Sky

Latin acidus, sour — sharing root with English acrid and acerbic. As a color modifier, acid implies a saturated-and-citric-and-zingy quality, the bright color of lemon-and-lime citrus-fruit-flesh and acid-yellow fluorescent-pigment surfaces. Sits at the bright-and-cool end of the grid, parallel to acidic and electric in usage.

Latin mira, wonderful-or-marvelous. As a color modifier, mira implies a variable-pulsing-and-red-giant-and-wondrous quality, the visual register of Cetus-Whale-and-variable-Mira-the-Wonder hand-variable-pulsing-and-red-giant-and-wondrous Cetus-Whale-and-variable-Mira-and-Hevelius-discovery mira-and-variable-pulsing-and-red-giant-and-wondrous surfaces under Cetus-Whale-and-variable-Mira-and-Hevelius-discovery 332-day-cycle-and-deep-red-pulse pulsing-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to nova and pulsar in usage.

The blue of a clear sky at noon — produced by Rayleigh scattering, the preferential dispersion of shorter wavelengths through atmospheric molecules. Air itself is colorless; the color we see is sunlight scattered toward our eyes by every cubic kilometer above. The reference shade is mid-latitude noon under a high pressure system: a clean, slightly green-shifted blue with the luminous depth of light scattered across an entire hemisphere of air.
