Abundant Sail Crimson
Abundant Sail Crimson (#AA2020) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (0°, 68%, 40%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin abundāre, to overflow — present-participle of abound. As a color modifier, abundant implies a saturated-and-plentiful quality where the hue carries surplus visual richness beyond minimum requirement. Sits at the bold-and-saturated end of the grid, parallel to plentiful and bountiful.
Old English segl, sail. As a color modifier, sail implies a wind-filled-canvas-cloth quality, the visual register of Tall-Ship-and-Royal-Navy-Sail hand-stitched wind-filled-canvas-and-flax-sail tall-ship-and-frigate maritime-rigging surfaces under wind-filled tall-ship-sail-and-canvas maritime light. Sits at the modifier-and-nautical end of the grid, parallel to mast and sheet in usage.
From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.

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.
