Majestic Rough Royal

#6380dd
Notes

Majestic Rough Royal (#6380DD) is a true blue with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (226°, 64%, 63%) 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.

Rough
modifier

Old English rūh, rough. As a color modifier, rough implies an unfinished-and-coarse quality, the visual register of unfinished-stone-and-burlap hand-quarried-and-unprocessed coarse-and-unfinished-textile-and-stone hand-quarried-and-coarse surfaces under hand-quarried-and-unfinished workshop-light. Sits at the modifier-and-texture end of the grid, parallel to hewn and bark in usage.

Royal
noun

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.

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.
