Majestic Chàm

#3643a2
Notes

Majestic Chàm (#3643A2) is a true blue 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 (233°, 50%, 42%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Majestic
adjective

Latin māiestātis, majesty — adjectival suffix -ic. As a color modifier, majestic implies a saturated-and-imposing-grandeur quality, the deep-rich color of Salisbury-Cathedral-and-Chartres-Cathedral Gothic-architecture monumental presence against the open sky. Sits at the bold-and-imposing end of the grid, parallel to regal and imperial.

Chàm
noun

The Vietnamese word for indigo — and vải chàm, the indigo-dyed cotton worn by H'mong, Tay, and Black Thai ethnic groups in Northern Vietnam. The color refers to a freshly chàm-dyed H'mong skirt: a saturated, slightly cool deep blue with the matte finish of multi-bath plant-dyed cotton.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
