Sanitary Surf
Sanitary Surf (#145374) is a deep azure with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (201°, 71%, 27%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin sānitās, health — adjectival suffix -ary. As a color modifier, sanitary implies a clear-and-clean-and-medical quality, the crisp color of Bauhaus-and-Modern clinical-and-hospital interior-architecture white-tile-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to hygienic and sterile in usage.
The white water produced where waves break — bubbles of compressed air carried in shallow water and dispersing as the wave reforms. The color refers to surf retreating across wet sand: a soft, very pale blue-green with the optical brightness of bubble dispersion. Lighter than seafoam, cooler than frost, with the kinetic weight of a color that's never still — every photograph of surf is already obsolete.
Closest matches
The nearest named color in three reference sources, ranked by perceptual distance (ΔE76 in CIELAB). ΔE < 1 is imperceptible to most viewers; ΔE > 10 is clearly different. When two sources point to the same hex they’re merged into one tile; click any to open that color’s page.

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.
