Ironclad Pelargonium

#b73493
Notes

Ironclad Pelargonium (#B73493) 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 (316°, 56%, 46%) 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

Ironclad
adjective

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.

Pelargonium
noun

South African Pelargonium genus — particularly the P. × hortorum and P. peltatum (zonal and ivy-leaved geraniums), cultivated worldwide for their deep-magenta-to-scarlet umbels. Pelargonium color refers to a fully bloomed P. × hortorum terminal umbel on a Mediterranean balcony: a saturated, slightly cool deep magenta with the velvet finish of fresh five-petaled flowers in dense radiating clusters. Greek pelargós (stork).
