Occluded Chrysoberyl
Occluded Chrysoberyl (#2E4B09) is a deep lime 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 (86°, 79%, 16%) places it in the highly saturated band at a dark 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin occludere, to close up — past-participle of occlude. As a color modifier, occluded implies a hue blocked-and-dimmed by an intervening physical barrier. Sits at the deep-and-obscured end of the grid, parallel to eclipsed and cloaked but more clinical in register.
A beryllium-aluminum oxide gem — particularly the chartreuse-green variety distinguished from emerald by its different chemistry. Mined principally in Brazil, Sri Lanka, and Madagascar. The color refers to a faceted Brazilian chrysoberyl: a saturated, slightly cool yellow-green with the gem's signature high refractive index.

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.
