Manorial Eupatorium
Manorial Eupatorium (#5B36B5) is a true indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (257°, 54%, 46%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin manōrium, dwelling — adjectival suffix -al, derived from manēre (to remain). As a color modifier, manorial implies a saturated-and-aristocratic-and-rural quality, the deep-rich color of pre-modern English manor-house livery-and-tapestry tradition. Sits at the bold-and-aristocratic end of the grid, parallel to lordly and patrician.
North American native Joe-Pye Weed (Eupatorium purpureum) — a six-foot-tall prairie perennial with terminal corymbs of dusty mauve-violet disk-flowers attractive to Monarchs in their fall migration. Eupatorium color refers to a fully bloomed Joe-Pye Weed corymb: a saturated, slightly cool deep blue-violet with the velvet finish of dense disk-flower clusters. Named for Mithridates Eupator, the herbal-medicine king of Pontus.

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.
This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
