Polished Yamaai
Polished Yamaai (#7678BC) 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°, 34%, 60%) 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
Latin polīre, to polish — past-participle of polish. As a color modifier, polished implies a clear-and-smooth-and-glossy quality where the hue carries the visual register of buffed-and-burnished smooth-finish surface. Sits at the crisp-and-finished end of the grid, parallel to burnished and gleaming in usage.
Japanese mountain indigo, Mercurialis leiocarpa — a wild herb used for dyeing in the Heian period (794–1185) before cultivated aizome indigo supplanted it. Yamaai color refers to a freshly yamaai-dyed silk: a saturated, slightly cool deep blue-violet with the matte finish of mineral-mordanted natural dye. The plant is the only naturally occurring indican-type indigo precursor in Japan.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
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.
