Rich Cartagena

#b7368a
Notes

Rich Cartagena (#B7368A) 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 (321°, 54%, 46%) 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

Rich
adjective

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

Cartagena
noun

Colombian Caribbean port city — once a Spanish-Habsburg colonial trade entrepôt, whose old-town Ciudad Amurallada district carries the iconic deep-magenta lime-stucco façades of cartagenera colonial architecture. Cartagena color refers to a Cartagena old-town stucco façade in late-afternoon light: a saturated, slightly cool deep magenta with the matte finish of lime-and-iron-oxide-pigmented colonial stucco.

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.
