Loud Hatiora
Loud Hatiora (#CE63AA) is a true magenta with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (320°, 52%, 60%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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 hlūd, making noise — borrowed metaphorically as a color word since the nineteenth century. Loud red, loud yellow: a color so saturated it announces itself without needing surrounding context. Sits in the bright-bucket extreme alongside electric and striking. Carries a slightly pejorative implication of excess.
Brazilian Easter cactus (Hatiora gaertneri) — a Cactaceae epiphytic cactus native to the southeastern Brazilian Mata Atlântica, with deep-magenta star-shaped flowers that bloom in spring around Easter. Hatiora color refers to a fully opened Hatiora gaertneri terminal flower in spring: a saturated, slightly cool deep magenta with the velvet finish of fresh radially symmetrical petaled corolla. Named for Thomas Hariot, Renaissance English natural historian.
