Direct Haori 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.

Japanese haori, short-jacket-over-kimono. As a color modifier, haori implies a Japanese-haori-and-short-jacket-over-kimono quality, the visual register of Edo-and-Meiji-haori-jacket hand-Japanese-haori-and-short-jacket-over-kimono Edo-and-Meiji-haori-jacket-and-Kyoto-Nishijin-and-Tokyo-Asakusa haori-and-Japanese-haori-and-short-jacket surfaces under Edo-and-Meiji-haori-jacket-and-Kyoto-Nishijin-and-Tokyo-Asakusa Edo-Tokugawa-and-Meiji-Tokyo Japanese-jacket-light. Sits at the modifier-and-textile end of the grid, parallel to kimono and sari 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.
