Tidy Pepper Sky

Old English tidig, timely — drifted in modern English to mean neat, orderly. Used as a color modifier for hues that read as composed and unfussy. Tidy beige, tidy gray: moderate saturation combined with optical neatness. Sits at the crisp-bucket alongside plain and modest.

Latin piper, black-pepper-corn. As a color modifier, pepper implies a black-pepper-corn-and-Malabar-Coast quality, the visual register of Malabar-Coast-and-Vietnamese-pepper hand-black-pepper-corn-and-Malabar-Coast Malabar-Coast-and-Vietnamese-pepper-and-Tellicherry pepper-and-black-pepper-corn surfaces under Malabar-Coast-and-Vietnamese-pepper-and-Tellicherry Malabar-and-Tellicherry-and-Phu-Quoc Indian-Ocean-spice-light. Sits at the modifier-and-flavor end of the grid, parallel to clove and cumin 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.
