Poised Tonbo

#1a79d6
Notes

Poised Tonbo (#1A79D6) 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°, 78%, 47%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Poised
adjective

Old French peser, to weigh — past-participle of poise. As a color modifier, poised implies a saturated-and-balanced-and-confident quality where the hue holds its position with elegant equilibrium. Sits at the bold-and-confident end of the grid, parallel to centered and composed.

Tonbo
noun

The Japanese word for dragonfly — and tonbo-iro, the iridescent blue-green of dragonfly wing membranes. Tonbo is also a samurai-era heraldic motif representing victory (katsumushi, victory-insect). The color refers to a male blue-tail dragonfly's abdomen at rest: a saturated, slightly cool iridescent deep blue with the satin finish of structurally colored insect cuticle.
