Grounded Tulum

#bb3582
Notes

Grounded Tulum (#BB3582) 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 (326°, 56%, 47%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Grounded
adjective

Old English grund, bottom / foundation — past-participle of ground. As a color modifier, grounded implies a saturated-and-foundational quality where the hue anchors the surrounding palette through its weighty presence. Sits at the bold-and-balanced end of the grid, parallel to centered and anchored.

Tulum
noun

Mayan archaeological site on the Mexican Caribbean coast — the Castillo and Templo del Dios Descendiente preserve the deep-magenta lime-mural pigments characteristic of Postclassic-period Yucatec Mayan monumental painting. Tulum color refers to a Tulum-period Mayan mural-fragment from the Templo de los Frescos: a saturated, slightly cool deep magenta with the matte finish of cochineal-and-cinnabar pigment on lime-plaster wall.

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.
