Effective Mulberry
Effective Mulberry (#D4C2FC) is a soft indigo with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (259°, 91%, 87%) places it in the highly saturated band at a light 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin effectīvus, productive — adjectival suffix -ive. As a color modifier, effective implies a clear-and-purpose-achieving quality where the hue carries the visual register of successful-task-completion design-element. Sits at the crisp-and-functional end of the grid, parallel to practical and useful in usage.
The genus Morus — the white mulberry (M. alba) feeds silkworms; the black mulberry (M. nigra) bears the deep purple fruit that stains everything it touches. The color refers to a ripe black mulberry: a saturated, slightly red-shifted very deep purple with the slight juiciness of a compound fruit. Cooler than wine, warmer than indigo, with the agricultural weight of a tree that supported the entire Chinese silk industry for two thousand years.

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.
