Shielded Akebia

#821789
Notes

Shielded Akebia (#821789) 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 (296°, 71%, 31%) 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.

As a color modifier, shielded implies a saturated-and-protected-and-defensive quality, the deep-rich color of medieval-knight armorial-shield-and-coat-of-arms heraldic display. Sits at the bold-and-fortified end of the grid, parallel to armored and bastioned.

Akebia
noun

Akebia color refers to a fully bloomed Akebia quinata female flower: a saturated, slightly cool deep violet with the velvet finish of fused-petaled cup-flower. The Japanese name akebi refers to the pendulous fruit pods.

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.
