Plumbed Stola
Plumbed Stola (#5F1691) is a deep indigo with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (276°, 74%, 33%) 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 plumbum, lead — past-participle of plumb (to measure depth with a lead-weighted line). As a color modifier, plumbed implies a deep-and-cool quality measured-to-its-fullest-depth, the dark cool-gray of lead-and-pewter metallic surfaces. Sits at the deep-and-cool end of the grid, parallel to fathomless with metallic register.
The Roman matron's long ceremonial robe — particularly the stola worn by Roman empresses and vestal virgins, often dyed in graduated Tyrian purple layers as a marker of social rank. Stola color refers to an imperial Roman Livia-period stola: a saturated, slightly cool deep violet with the matte finish of multi-bath Tyrian shellfish-dye on Roman wool. Distinct from the unmarried-woman tunica and the slave colobium.

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.
