Wan Aizu
Wan Aizu (#969CBB) is a true 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 (230°, 21%, 66%) places it in the muted 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
Old English wann, dark / gloomy (semantic shift to pale by Middle English). As a color modifier, wan implies a pale-and-drained-of-vitality quality where the hue carries the visual register of Edwardian-period pale-and-faintly-tinted dimmed lighting interior color. Sits at the pale-and-drained end of the grid, parallel to pallid and pasty in usage.
Japanese feudal domain (Aizu-han) of the Edo period — a samurai region in modern Fukushima famous for aizu-momen, the indigo-dyed cotton woven by samurai-class women during the Tokugawa shogunate's lean years. Aizu color refers to a freshly aizu-momen-woven indigo cotton: a saturated, slightly cool deep blue-violet with the matte finish of multi-bath natural indigo on hand-spun cotton.

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.
This color sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
