Rich Zenith Bougainvillea

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

Arabic samt-al-ra's, path-overhead. As a color modifier, zenith implies an overhead-pointing-and-high-point quality, the visual register of celestial-sphere-and-overhead-Zenith hand-overhead-pointing-and-high-point celestial-sphere-and-overhead-and-Zenith-pole zenith-and-overhead-pointing-and-high-point surfaces under celestial-sphere-and-overhead-and-Zenith-pole astronomical-and-celestial-mechanics overhead-axis-light. Sits at the modifier-and-cosmic end of the grid, parallel to nadir and axis in usage.

The genus Bougainvillea — South American vines named for the French explorer Louis Antoine de Bougainville, whose 1768 voyage encountered the plant in Rio de Janeiro. The color refers to the bracts (modified leaves) of a vivid magenta Bougainvillea spectabilis: a saturated, slightly cool deep pink-magenta with the matte papery finish of bracts that surround the plant's tiny actual flowers. Brighter than fuchsia, cooler than coral.
