Aligned Alpine

#288ab7
Notes

Aligned Alpine (#288AB7) is a true cyan 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 (199°, 64%, 44%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Aligned
adjective

French à-ligne, to-line-up — past-participle of align. As a color modifier, aligned implies a clear-and-axis-coordinated quality where the hue carries the visual register of carefully-parallel-arranged elements. Sits at the crisp-and-balanced end of the grid, parallel to symmetrical and squared in usage.

Alpine
noun

Of the Alps, the European mountain range — and the saturated blue of Alpine lake water (Lake Geneva, Lake Como, Lake Brienz) fed by glacier-melt. Alpine color refers to Lake Brienz at midday: a saturated, slightly cool deep blue with the optical clarity of glacier-fed alpine lake water.
