Spick Nadir Ocean

Old Norse spik-spakr, spike-new — sharing root with spic-and-span. As a color modifier, spick implies a clear-and-newly-cleaned quality where the hue carries the just-polished visual register of fresh-painted-and-fresh-cleaned surfaces. Sits at the crisp-and-clean end of the grid, parallel to spotless and pristine in usage.

Arabic naẓīr, opposite-of-zenith. As a color modifier, nadir implies a downward-pointing-and-low-point quality, the visual register of celestial-sphere-and-downward-Nadir hand-downward-pointing-and-low-point celestial-sphere-and-downward-and-Nadir-pole nadir-and-downward-pointing-and-low-point surfaces under celestial-sphere-and-downward-and-Nadir-pole astronomical-and-celestial-mechanics downward-axis-light. Sits at the modifier-and-cosmic end of the grid, parallel to zenith and axis in usage.

The body of saltwater that covers seventy percent of Earth's surface — a single connected mass divided by convention into Atlantic, Pacific, Indian, Southern, and Arctic. The color refers to the average reflectance of mid-depth temperate ocean: a saturated, slightly green-shifted deep blue with the optical depth of a body of water that absorbs all light below the photic zone. Deeper than mediterranean, cooler than peacock.
