Cool Asparagus
Cool Asparagus (#B1E18C) is a soft lime 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 (94°, 59%, 72%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English cōl, of low temperature — used as a color modifier as the complement to warm. Cool gray, cool blue: the optical impression of a slight blue-green shift, even within otherwise warm or neutral hues. Sits across the crisp, hushed, pale, and neutral buckets.
Asparagus officinalis, the cultivated perennial whose tender spring shoots have been a delicacy since Mediterranean antiquity — Apicius gives a recipe in the first century. The color refers to the tip of a fresh asparagus spear: a soft, slightly yellow-shifted green with the matte finish of a young plant stem. Cooler than pear, warmer than sage, with the seasonal weight of a vegetable available only briefly each year.
