Rugged Camas

#336ad1
Notes

Rugged Camas (#336AD1) is a true azure 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 (219°, 63%, 51%) 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

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.

Camas
noun

The genus Camassiacamas lily, North American native bulbs whose deep-blue flower spikes were a staple food source for Pacific Northwest Indigenous peoples (the bulbs are cooked in pit ovens). The color refers to a C. quamash meadow at peak bloom: a saturated, slightly cool deep blue with the satin finish of six-petaled lily-form flower.

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.
