Tough Nadir violet

Old English tōh, firm / tenacious — sharing root with German zäh. As a color modifier, tough implies a saturated-and-resilient quality where the hue resists fading-and-modulation through its strong pigmentation. Sits at the bold-and-resilient end of the grid, parallel to rugged and hardy 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.

Viola odorata, the European sweet violet — small, fragrant, and the original meaning of the color name in English (the Violet of the rainbow). The color refers to a fresh sweet violet blossom in late winter: a saturated, slightly red-shifted deep blue-purple with the matte finish of small five-petaled flower. Cooler than amethyst, warmer than indigo, with the perfumed weight of a flower used in Roman garlands and Victorian eau de toilette.
