Saturated Wink Sapphire

#313bad
Notes

Saturated Wink Sapphire (#313BAD) 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 (235°, 56%, 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Saturated
adjective

From the Latin saturatus, past participle of saturare, to fill. A technical color term in modern usage — saturation is one of the three axes of HSL (with hue and lightness). As a modifier, saturated implies that the hue is at or near its maximum chromatic intensity. Sits at the bold-and-bright top of the grid.

Wink
modifier

Old English wincian, to-close-eye-briefly. As a color modifier, wink implies a brief-and-coy-and-twinkling quality, the visual register of star-and-candle-flame-wink hand-brief-and-coy-and-twinkling star-and-candle-flame-and-distant-window winked-and-brief-and-coy-and-twinkling surfaces under star-and-candle-flame-and-distant-window twinkling-and-coy-and-brief night-window-light. Sits at the modifier-and-mood end of the grid, parallel to blink and glint in usage.

Sapphire
noun

An iron-and-titanium-bearing corundum — the same mineral as ruby, hardness 9 on the Mohs scale, mined for two millennia from Sri Lanka, Burma, Madagascar, and the Cashmere mines of British India. The color refers to a fine Kashmir-cut sapphire: a saturated, slightly violet-shifted deep blue with the gem's signature internal velvet — a quality of light scattering in the stone that faceted glass cannot replicate. Cooler than cobalt, deeper than azure.

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.
