Steadfast Stokesia
Steadfast Stokesia (#6155E8) 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 (245°, 76%, 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English stede-fæst, fixed in place — sharing root with German stetig. As a color modifier, steadfast implies a saturated-and-unwavering quality where the hue maintains its visual character without modulation. Sits at the bold-and-firm end of the grid, parallel to unwavering and firm in usage.
North American Stokes' aster (Stokesia laevis) — a southeastern-coastal-plain Asteraceae native cultivated as a ground-cover perennial with fringed lavender ray-flowers. Stokesia color refers to a fully opened Stokesia laevis flower head: a saturated, slightly cool deep blue-violet with the velvet finish of finely fringed ray-flowers around a paler central disk. Named for Jonathan Stokes, an English physician-botanist of the 18th century.
