Established Suo
Established Suo (#8F177C) is a deep magenta 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 (310°, 72%, 33%) 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
Latin stabilīre, to make stable — past-participle of establish. As a color modifier, established implies a saturated-and-rooted quality where the hue carries the weight of long-standing visual presence. Sits at the bold-and-firm end of the grid, parallel to steadfast and anchored in usage.
Japanese 蘇芳, sappan-wood dye (Caesalpinia sappan) — derived from a Southeast Asian tree's heartwood, imported to Japan since the Nara period (710–794) for dyeing court robes a deep red-purple. Suo color refers to a suo-dyed Heian-period silk kinu: a saturated, slightly cool deep magenta with the silk luster of multi-bath sappan-wood dye on tussah silk. Distinct from akane (madder) and beni (safflower).
