Cellared Acanthus
Cellared Acanthus (#492381) 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 (264°, 57%, 32%) 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 cellārium, storehouse — past-participle of cellar. As a color modifier, cellared implies the deep-and-cool-and-architectural quality of Bordeaux-and-Burgundy wine-cellar underground stone-and-oak storage-chamber, with the patina of multi-decade barrel-aging-and-bottle-laying. Sits at the deep-and-architectural end of the grid, parallel to crypted with viticulture register.
Mediterranean Acanthus mollis and A. spinosus — the bear's breeches, whose deeply scalloped leaves furnished the Corinthian capital's signature ornamental motif since the 5th century BCE. Acanthus color refers to a fully bloomed Acanthus mollis flower spike: a saturated, slightly cool deep blue-violet with the velvet finish of two-lipped tubular flowers in a tall hooded spike. Foundational to the Western architectural ornamental vocabulary.

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.
