Pressing Concord
Pressing Concord (#411D6B) is a deep indigo 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 (268°, 57%, 27%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin pressāre, to press repeatedly — present-participle of press. As a color modifier, pressing implies a deep-and-imposing-and-weighty quality where the hue exerts visual force on its substrate. Sits at the deep-and-weighty end of the grid, parallel to crushing with insistent register.
Vitis labrusca, the Concord grape — bred in 1849 by Ephraim Wales Bull in Concord, Massachusetts, and the foundation of American grape juice and the kosher Manischewitz wine industry. The color refers to a ripe Concord grape on the vine: a saturated, slightly red-shifted very deep purple with the heavy bloom of waxy fruit surface. Cooler than wine, warmer than indigo, with the lunchbox-and-Welch's weight of a New England crop that changed an entire continent's beverage culture.

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.
