Sturdy Genji

#542fa5
Notes

Sturdy Genji (#542FA5) 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 (259°, 56%, 42%) 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

Sturdy
adjective

Old French estourdi, stunned, reckless — drifted in English to mean robust, well-built. Used as a color modifier since the seventeenth century for hues that read as durable and unfussy — the working browns of saddle leather, the working greens of pasture wool. Sits in the bold-and-warm corner alongside robust and solid.

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.

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.
