Cool Sari Sky

Old English cōl, of low temperature — used as a color modifier as the complement to warm. Cool gray, cool blue: the optical impression of a slight blue-green shift, even within otherwise warm or neutral hues. Sits across the crisp, hushed, pale, and neutral buckets.

Sanskrit śāṭī, long-draped-cloth. As a color modifier, sari implies an Indian-sari-and-Banarasi-and-Kanjeevaram-silk quality, the visual register of Banarasi-and-Kanjeevaram-sari hand-Indian-sari-and-Banarasi-and-Kanjeevaram-silk Banarasi-and-Kanjeevaram-sari-and-Mysore-and-Bengal-cotton sari-and-Indian-sari surfaces under Banarasi-and-Kanjeevaram-sari-and-Mysore-and-Bengal-cotton Varanasi-and-Kanjeevaram-and-Mysore-loom Indian-loom-light. Sits at the modifier-and-textile end of the grid, parallel to kimono and haori 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.
