Steadfast Asparagus
Steadfast Asparagus (#659C1A) is a true lime 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 (85°, 71%, 36%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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 stede-fæst, fixed in place — sharing root with German stetig. As a color modifier, steadfast implies a saturated-and-unwavering quality where the hue maintains its visual character without modulation. Sits at the bold-and-firm end of the grid, parallel to unwavering and firm in usage.
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.
