Decisive Lilac

#8c1684
Notes

Decisive Lilac (#8C1684) 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 (304°, 73%, 32%) 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

Decisive
adjective

From the Latin decidere, to cut off — used as a modifier for colors that read as firm and final. Decisive black, decisive red: the implication is that the color has settled on its position and won't drift. Sits in the bold-bucket corner alongside resolute, with a slightly sharper edge.

Lilac
noun

Syringa vulgaris, the Balkan-native shrub whose pale purple panicles perfume European gardens in May. The Persian nilak, bluish, became the Arabic līlak and then the Spanish lila before reaching English in the seventeenth century. The color refers to a fresh lilac flower cluster: a soft, slightly muted pale purple with the matte finish of densely packed four-petaled florets. Lighter than mauve, cooler than orchid.

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.
