Sparkling Andalusite
Sparkling Andalusite (#FEC73B) is a true amber with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (43°, 99%, 61%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English spearca, spark — present-participle of sparkle. As a color modifier, sparkling implies a saturated-and-multi-point-reflective-and-effervescent quality, the bright color of Champagne-and-Prosecco effervescent-wine carbonation-bubble-light reflection. Sits at the bright-and-reflective end of the grid, parallel to glittering and fizzy in usage.
An aluminum silicate gem — pleochroic from yellow-brown to gold-green to red-brown depending on viewing angle. Mined principally in Brazil and Sri Lanka. The color refers to a faceted Brazilian andalusite seen along its strong axis: a soft, slightly muted warm gold-brown with the optical complexity of pleochroic stone.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
