Fortified Bell violet

Latin fortificāre, to make strong — past-participle of fortify. As a color modifier, fortified implies a saturated-and-strengthened-and-defensive quality, the deep-rich color of Vauban-style military-fortification stone-and-earth rampart-and-bastion architecture. Sits at the bold-and-fortified end of the grid, parallel to bastioned and armored.

Old English belle, bell. As a color modifier, bell implies a hour-marked-and-tolling quality, the visual register of English-and-Russian-bell-tower hour-marking-and-tolling cathedral-bell-and-bell-tower clock-and-time-marking surfaces under hour-marked-bell tolling-bell-tower light. Sits at the modifier-and-time end of the grid, parallel to knell and hour 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.
