Plotted Hermes Sky

Old English plot, small piece of ground — past-participle of plot. As a color modifier, plotted implies a clear-and-coordinate-mapped quality, the crisp color of Cartesian-and-graph-paper coordinate-plotted scientific-and-engineering data-visualization plot-line. Sits at the crisp-and-mapped end of the grid, parallel to mapped and surveyed in usage.

Greek Ἑρμῆς, messenger-of-the-Olympian-gods. As a color modifier, hermes implies a winged-sandal-and-caduceus-and-messenger quality, the visual register of Praxiteles-Hermes-and-Olympia-marble hand-winged-sandal-and-caduceus-and-messenger Praxiteles-Hermes-and-Olympia-marble-and-Hellenistic-bronze hermes-and-winged-sandal-and-caduceus surfaces under Praxiteles-Hermes-and-Olympia-marble-and-Hellenistic-bronze Olympian-pantheon-and-marketplace Mediterranean-marble-light. Sits at the modifier-and-myth end of the grid, parallel to zeus and atlas 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.
