Solid Susa
Solid Susa (#93259B) is a true 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°, 61%, 38%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin solidus, firm, dense — used as a color modifier since the seventeenth century for hues that read as continuous and unbroken: a solid blue is one with no variation across the surface. Implies high saturation combined with optical density. Sits in the bold-bucket alongside strong and robust, slightly more focused on uniformity.
Persian Achaemenid winter capital — and the imperial court color storehouse for Tyrian purple tribute textiles imported from Phoenician Tyre and Sidon under Darius I (522–486 BCE). Susa color refers to a Susa-stored Achaemenid royal kandys coat: a saturated, slightly cool deep violet with the matte finish of multi-bath shellfish-dye on Persian-court silk-and-wool blend.
