Frantic Woad
Frantic Woad (#4FEFE9) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (178°, 83%, 62%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Greek phrenitikós, frenzied — adjectival suffix, sharing root with phrenitis (delirium). As a color modifier, frantic implies a saturated-and-rushed-and-overactive quality, the bright color of Memphis-Group 1980s-design over-the-top saturated visual-rhythm. Sits at the bright-and-active end of the grid, parallel to frenetic and manic in usage.
Isatis tinctoria, the European blue-dye plant whose leaves yield indigo-equivalent indigotin. Used by Pictish warriors as body paint and the dominant pre-industrial European blue dye until East Indian indigo displaced it in the seventeenth century. The color refers to a freshly woad-dyed wool: a saturated, slightly cool deep blue with the matte finish of plant-and-mordant dye.

How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
