Blue

Blue (#0000FF) 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 (240°, 100%, 50%) 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. Pure B=255 — the blue vertex of the RGB cube, and the third of the three additive primaries. One of the 16 HTML 3.2 named colors (1997).
