Magisterial Genji

#642ec5
Notes

Magisterial Genji (#642EC5) is a true 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 (261°, 62%, 48%) 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

Magisterial
adjective

Latin magisterium, teacher's office — adjectival suffix -al. As a color modifier, magisterial implies a saturated-and-authoritative-and-formal quality, the deep-rich color of Qing-dynasty civil-magistrate court-and-ritual textiles and Imperial-Examination scholar-class livery. Sits at the bold-and-authoritative end of the grid, parallel to authoritative and commanding.

Genji
noun

The eponymous nobleman of The Tale of Genji (Genji Monogatari, 1010 CE) by Murasaki Shikibu, whose silk-on-silk court robes were dyed in graduated layers of murasaki and aizome. Genji color refers to a layered Heian-period court robe in the kasane no irome tradition: a saturated, slightly cool deep blue-violet with the silk luster of multi-layer kasane dyeing.

Display P3 representation

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.
