Strobing Alcove Jade
Strobing Alcove Jade (#17AE79) is a true teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (159°, 77%, 39%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Greek stróbos, whirling — present-participle of strobe. As a color modifier, strobing implies a saturated-and-pulse-flashing quality, the bright color of concert-strobe-light and photographic-strobe high-frequency-pulse light emission. Sits at the bright-and-flashing end of the grid, parallel to flashing and pulsating in usage.
Arabic al-qubba, the-vault. As a color modifier, alcove implies a recessed-bedroom-or-sitting-area quality, the visual register of English-and-French-Country-House-alcove hand-built recessed-and-vaulted bedroom-or-sitting-area-recess-and-window-seat architectural surfaces under English-and-French-Country-House alcove-recess light. Sits at the modifier-and-architecture end of the grid, parallel to niche and atrium in usage.
Two minerals share the name: nephrite (a calcium-magnesium silicate, dominant in Chinese jade) and jadeite (a sodium-aluminum silicate, dominant in Burmese imperial jade). Both have been carved in China since at least the Neolithic. The color refers to high-quality apple-green jadeite: a saturated, slightly muted yellow-green with the waxy translucency of polished stone. Cooler than apple, warmer than mint, with the millennial cultural weight of yu, the stone of heaven.
