Reinforced Logwood
Reinforced Logwood (#5755EA) is a true blue with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (241°, 78%, 63%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary yellow. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin re- plus inforce — past-participle of reinforce. As a color modifier, reinforced implies a saturated-and-doubled-up-and-strengthened quality where the hue carries layered pigmentation for maximum visual presence. Sits at the bold-and-fortified end of the grid, parallel to fortified and buttressed.
Central American Haematoxylum campechianum — a tropical legume tree native to Yucatán and Belize, whose heartwood was the colonial-era principal source of haematein and hematoxylin dyes (also used for histology staining). Logwood color refers to a freshly logwood-mordant-dyed wool: a saturated, slightly cool deep blue-violet with the matte finish of haematein-on-iron-mordanted woolen fiber. Also the campeche of European calligraphy ink.
