Wired Cobaltite
Wired Cobaltite (#4394E3) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (210°, 74%, 58%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English wīr, wire — past-participle of wire. As a color modifier, wired implies a saturated-and-electrical-charged-and-active quality, the bright color of Tesla-coil-and-Van-de-Graaff high-voltage atmospheric-electrical emission. Sits at the bright-and-active end of the grid, parallel to charged and electrified in usage.
A cobalt-arsenic-sulfide mineral — the principal historical source of cobalt for ceramic and pigment use. Mined principally in Cobalt, Ontario (the source of the modern cobalt-mining industry's name). The color refers to a polished cobaltite crystal: a soft, slightly cool deep blue-silver with the metallic finish of crystallized cobalt mineral.

Accessibility
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.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
