Authoritative Cartagena

#c13998
Notes

Authoritative Cartagena (#C13998) 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°, 54%, 49%) 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

Authoritative
adjective

Latin auctōritāt-, authority — adjectival suffix -ive. As a color modifier, authoritative implies a saturated-and-formal-imperative quality where the hue carries decisional weight and institutional credibility. Sits at the bold-and-authoritative end of the grid, parallel to commanding and magisterial in usage.

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.
