Plutonian Tulip

#6a1e78
Notes

Plutonian Tulip (#6A1E78) is a deep violet 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 (291°, 60%, 29%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plutonian
adjective

From Pluto, the Roman god of the underworld (Greek Plouton). As a color modifier, plutonian implies the cool deep darkness of the underworld realms, with literary-classical register. Sits at the deep-and-cool end of the grid, parallel to Hadean and cooler than infernal.

Tulip
noun

The genus Tulipa — Central Asian bulbs cultivated in Ottoman gardens, brought to Europe in the sixteenth century, and famously the subject of tulipomania in the 1630s Dutch Republic. The color refers to a deep purple Tulipa hybrid in spring bloom: a saturated, slightly red-shifted deep purple with the satiny finish of a six-petaled goblet. Cooler than orchid, warmer than indigo, with the cultivation history of a flower that briefly cost more than houses.

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.
