Diluted Anil
Diluted Anil (#AEAECE) is a soft 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 (240°, 25%, 75%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin dīluere, to wash away — past-participle of dilute. As a color modifier, diluted implies a pale-and-water-thinned quality where the hue has been substantially mixed with neutral-or-water medium to reduce its saturation. Sits at the pale-and-diluted end of the grid, parallel to watery and thinned in usage.
Portuguese and Spanish for Indigofera tinctoria — derived via the Arabic al-nīl from the Sanskrit nīla (dark blue), the colonial-era European name for indigo before indigo itself supplanted it in the 18th century. Anil color refers to a freshly anil-dyed Portuguese azulejo-period linen: a saturated, slightly cool deep blue-violet with the matte finish of multi-bath fermentation indigo on hand-spun linen.

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.
