Hefty Tulum

#913575
Notes

Hefty Tulum (#913575) is a true magenta with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (318°, 46%, 39%) 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

Hefty
adjective

Old English hefig, heavy — adjectival suffix -y. As a color modifier, hefty implies a saturated-and-substantial-and-weighty quality where the hue carries the visual heft of a hand-cast pig-iron object. Sits at the bold-and-weighty end of the grid, parallel to substantial and weighty in usage.

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.
