Suffused Patagonia
Suffused Patagonia (#222D7A) 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 (233°, 56%, 31%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin suffundere, to pour beneath — past-participle of suffuse. As a color modifier, suffused implies a deep-saturation-and-warmth where the hue has been infused with pigment from within. Sits at the deep-and-saturated end of the grid, parallel to infused and warmer than drenched.
The southern South American region — Chile and Argentina — and the saturated deep blue of Lago Argentino, Perito Moreno Glacier, and the Patagonian summer sky. Patagonia refers to Lago Argentino at midday: a saturated, slightly cool deep blue with the optical depth of glacier-fed Patagonian lake.

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.
