Sharp Bow Sky

Old English scearp, cutting, pointed — applied metaphorically to color since the seventeenth century for hues that read as definite and edge-defined. Sharp red, sharp green: the implication is saturation combined with high-contrast crispness. Sits in the bright-bucket center alongside crisp and clear, with a slightly more incisive edge.

Old Norse bógr, bow / shoulder. As a color modifier, bow implies a ship's-front-prow quality, the visual register of Royal-Navy-and-merchant-marine-bow hand-built ship's-front-prow-and-figurehead bow-and-cutwater maritime-architecture surfaces under ship's-front-bow-and-prow maritime-headway light. Sits at the modifier-and-nautical end of the grid, parallel to prow and hull 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.
