Vaulted Sapporo
Vaulted Sapporo (#222A82) is a deep blue with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (235°, 59%, 32%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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.
Etymology
Old French voulte, vault via Latin volūta (rolled) — past-participle of vault. As a color modifier, vaulted implies the deep-and-architectural-and-Gothic quality of Salisbury-Cathedral-and-Chartres-Cathedral nave-vault overhead-stone-arched ceiling. Sits at the deep-and-architectural end of the grid, parallel to cavernous with cathedral-vault register.
Capital of Japan's Hokkaido island — a city famous for its annual February Yuki Matsuri (Snow Festival) with deep-twilight blue lighting on illuminated snow sculptures along the Ōdōri Park boulevard. Sapporo color refers to a Yuki Matsuri night-sky over an illuminated snow sculpture: a saturated, slightly cool deep blue-violet with the optical complexity of artificial illumination on snow-reflected sky.

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.
