Honest Muse Sky

Latin honestus, honorable — used as a color modifier since the seventeenth century for hues that read as straightforward and unembellished, the working browns and grays of vernacular architecture rather than the polished shades of court fashion. Honest brown, honest gray: moderate saturation combined with optical directness. Sits at the crisp-bucket alongside plain and frank.

Latin Musa, goddess-of-inspiration. As a color modifier, muse implies a contemplative-and-inspired-and-poetic quality, the visual register of Helicon-spring-and-Parnassus-muse hand-contemplative-and-inspired-and-poetic Helicon-spring-and-Parnassus-and-Castalian-fount mused-and-contemplative-and-inspired-and-poetic surfaces under Helicon-spring-and-Parnassus-and-Castalian-fount laurel-and-lyre-and-tablet poet's-grove-light. Sits at the modifier-and-mood end of the grid, parallel to mull and brood 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.
