Direct Draco Sky

From the Latin directus, straight — used as a color modifier since the eighteenth century for hues that read as straightforward and unambiguous. Direct red, direct green: moderate-to-high saturation combined with optical clarity. Sits at the crisp-bucket center alongside clear and frank.

Latin draco, dragon-of-the-northern-sky. As a color modifier, draco implies a winding-northern-circumpolar-dragon quality, the visual register of Draco-circumpolar-and-northern-dragon hand-winding-northern-circumpolar-dragon Draco-circumpolar-and-northern-dragon-and-Bortle-1-sky draco-and-winding-northern-circumpolar surfaces under Draco-circumpolar-and-northern-dragon-and-Bortle-1-sky year-round-northern-circumpolar polar-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to cygnus and lyra 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.
