Rugged Sundown

#6a6ecc
Notes

Rugged Sundown (#6A6ECC) 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 (238°, 49%, 61%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Rugged
adjective

Old Norse rugga, rough / coarse — adjectival suffix -ed. As a color modifier, rugged implies a saturated-and-rough-and-weathered quality, the deep-rich color of Scottish-Highlands-and-Norwegian-fjord outdoor-and-mountain landscape. Sits at the bold-and-weathered end of the grid, parallel to tough and sinewy in usage.

Sundown
noun

English compound for the moment of sunset's last upper-limb contact with the horizon — the brief window when the eastern anti-solar sky is at its deepest Belt of Venus indigo before nightfall. Sundown color refers to a clear-sky eastern anti-solar horizon at sundown: a saturated, slightly cool deep blue-violet with the optical complexity of Rayleigh-scattered Belt of Venus light against the rising Earth shadow.

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.
