Mapped Porpora

#813829
Notes

Mapped Porpora (#813829) is a deep red with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (10°, 52%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Mapped
adjective

Latin mappa, cloth / napkin — past-participle of map. As a color modifier, mapped implies a clear-and-cartographic-and-surveyed quality, the crisp color of Ordnance-Survey-and-USGS scientific-and-cadastral cartographic-and-topographic mapping-and-projection. Sits at the crisp-and-mapped end of the grid, parallel to plotted and surveyed in usage.

Porpora
noun

The Italian word for the imperial purple of Roman tradition — derived from murex shells but borrowed in modern Italian color vocabulary for a deep, slightly red-shifted purple-red. The color refers to porpora-dyed Venetian silk: a saturated, slightly cool deep red-purple with the satin finish of plant-and-shell dye. Cooler than crimson, warmer than burgundy.
