Grounded Zànglán

#507fe7
Notes

Grounded Zànglán (#507FE7) 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 (221°, 76%, 61%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Grounded
adjective

Old English grund, bottom / foundation — past-participle of ground. As a color modifier, grounded implies a saturated-and-foundational quality where the hue anchors the surrounding palette through its weighty presence. Sits at the bold-and-balanced end of the grid, parallel to centered and anchored.

Zànglán
noun

Chinese zànglán (藏蓝) — Tibetan blue or storage blue, the saturated deep blue of Tibetan-Buddhist monastery wall paint and Tibetan textile dye. The color refers to a zànglán-painted Lhasa monastery interior: a saturated, slightly cool deep blue with the matte finish of mineral-pigment-on-plaster.

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.
