Imperial Cartagena

#a6428b
Notes

Imperial Cartagena (#A6428B) 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 (316°, 43%, 45%) 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

Imperial
adjective

From the Latin imperialis, of the empire — applied to color since the medieval period for the hues reserved for sovereigns and empires: imperial purple of Tyrian dye, imperial yellow of Ming-dynasty porcelain. As a modifier, imperial implies saturation combined with the institutional weight of a color owned by a court. Sits in the bold-and-deep corner, alongside royal.

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.
