Spirited Nebula Chartreuse
Spirited Nebula Chartreuse (#B4B506) is a true yellow with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (60°, 94%, 37%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
An adjectival form of spirit — used as a color modifier since the seventeenth century for hues that read as animate and characterful. Spirited orange, spirited green: the implication is saturation combined with personality, a color that feels like it has agency. Sits at the bright-bucket center alongside lively and vibrant.
Latin nebula, mist-or-cloud. As a color modifier, nebula implies a glowing-cloud-and-stellar-cradle quality, the visual register of Orion-and-Eagle-Nebula hand-glowing-cloud-and-stellar-cradle Orion-and-Eagle-and-Crab-Nebula nebula-and-glowing-cloud-and-stellar-cradle surfaces under Orion-and-Eagle-and-Crab-Nebula Hubble-and-James-Webb-deep-field stellar-cradle-light. Sits at the modifier-and-cosmic end of the grid, parallel to plasma and meteor in usage.
The yellow-green French liqueur made by Carthusian monks at the Grande Chartreuse monastery since 1737, from a recipe of 130 herbs known to only two living monks at any time. The color is the base spirit chartreuse jaune in a glass: a saturated, slightly green yellow that's brighter than lemon and warmer than lime. The liqueur gave the color its name, not the other way around.

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.
