Centered Klein
Centered Klein (#2952CB) 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 (225°, 66%, 48%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin centrum, center — past-participle of center. As a color modifier, centered implies a saturated-and-grounded-and-balanced quality where the hue occupies the visual center of its palette without drift. Sits at the bold-and-balanced end of the grid, parallel to poised and grounded.
Yves Klein, the French artist (1928–1962) who patented International Klein Blue (IKB) in 1960 — a synthetic ultramarine suspended in a binder that preserved the matte saturation of the raw pigment. The color refers to a Klein monochrome painting: a deeply saturated, slightly violet-shifted blue with the velvet-matte finish of un-glossed pigment. Deeper than ultramarine, cooler than royal, with the art-world specificity of a color owned, briefly, by one artist.
