Ironclad Lac
Ironclad Lac (#A52A8A) is a true magenta with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (313°, 59%, 41%) 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
English compound iron + clad — referring to the 19th-century USS-Monitor and CSS-Virginia iron-armored warships. As a color modifier, ironclad implies a saturated-and-armored-and-impenetrable quality where the hue carries the visual weight of forged-iron armor-plate. Sits at the bold-and-fortified end of the grid, parallel to fortified and armored.
Indian and Southeast Asian lac insect (Kerria lacca) — a small scale insect that secretes a deep-magenta resinous coating on host-tree branches, harvested for shellac varnish and lac dye. Lac color refers to a freshly lac-dyed Indian wool namda felt rug: a saturated, slightly cool deep magenta with the matte finish of multi-bath insect-resin-dyed wool. The English word lacquer comes from the same root.
