Dappled Aconitum
Dappled Aconitum (#A8BCD0) is a soft azure 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 (210°, 30%, 74%) places it in the balanced 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 Norse depill, spot / pool — past-participle of dapple. As a color modifier, dappled implies a pale-and-mottled-and-light-and-shadow-spotted quality, the pale color of summer-orchard sun-through-leaves dappled-light-and-shadow ground-pattern surface. Sits at the pale-and-soft end of the grid, parallel to speckled and mottled in usage.
The genus Aconitum — monkshood, the highly toxic European perennial whose deep blue-purple hooded flowers contain aconitine alkaloid (poisonous enough to kill on skin contact). The color refers to a fresh A. napellus in late summer: a saturated, slightly cool deep blue-violet with the matte finish of helmet-shaped flower.

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.
