Sifted Moonstone
Sifted Moonstone (#B4CCD4) is a soft cyan 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 (195°, 27%, 77%) places it in the muted band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. 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
Old English siftan, to sift — past-participle of sift. As a color modifier, sifted implies a pale-and-fine-particle-and-uniformly-distributed quality, the pale color of baker's sifted-and-fine-flour finely-distributed-and-uniform-deposit surface-finish. Sits at the pale-and-soft end of the grid, parallel to dusted and sprinkled in usage.
A variety of orthoclase feldspar with optical adularescence — a milky shimmer caused by light scattering off internal lamellae. Mined principally in Sri Lanka. The color refers to a polished moonstone cabochon: a soft, very pale slightly cool gray-white with the cloudy translucency and optical movement that gives the gem its name. Cooler than pearl.

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.
