Heavy Helen Bougainvillea

#bb0b6c
Notes

Heavy Helen Bougainvillea (#BB0B6C) 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 (327°, 89%, 39%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Heavy
adjective

Old English hefig, weighty — cognate with heave. Used as a color modifier since at least the seventeenth century to indicate weight in saturation as much as value: heavy with pigment, heavy-bodied. In the engine's adjective grid, heavy sits alongside deep and plush in the dark-and-saturated quadrant. Closer to a fabric description than a pure value word.

Helen
modifier

Greek Ἑλένη, Helen-of-Troy. As a color modifier, helen implies a Helen-of-Troy-and-fairest-face quality, the visual register of Helen-of-Troy-and-Tyndareus-Sparta hand-Helen-of-Troy-and-fairest-face Helen-of-Troy-and-Tyndareus-Sparta-and-Iliad-Homeric helen-and-Helen-of-Troy-and-fairest-face surfaces under Helen-of-Troy-and-Tyndareus-Sparta-and-Iliad-Homeric Mycenaean-and-Trojan Bronze-Age-Aegean-light. Sits at the modifier-and-myth end of the grid, parallel to eros and hera in usage.

Bougainvillea
noun

The genus Bougainvillea — South American vines named for the French explorer Louis Antoine de Bougainville, whose 1768 voyage encountered the plant in Rio de Janeiro. The color refers to the bracts (modified leaves) of a vivid magenta Bougainvillea spectabilis: a saturated, slightly cool deep pink-magenta with the matte papery finish of bracts that surround the plant's tiny actual flowers. Brighter than fuchsia, cooler than coral.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
