Cool Shikon
Cool Shikon (#F4AAE7) is a soft magenta with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (311°, 77%, 81%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English cōl, of low temperature — used as a color modifier as the complement to warm. Cool gray, cool blue: the optical impression of a slight blue-green shift, even within otherwise warm or neutral hues. Sits across the crisp, hushed, pale, and neutral buckets.
Japanese 紫根, gromwell root (Lithospermum erythrorhizon) — the purple-root dye source for traditional Japanese murasaki and the medicinal-herb base for the eponymous shikon ointment used in burn treatment. Shikon color refers to a freshly harvested Lithospermum erythrorhizon root cross-section: a saturated, slightly cool deep violet with the matte finish of fresh root dye on hand-spun silk.
