Fiery Ivy
Fiery Ivy (#9DEF99) is a soft green 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 (117°, 73%, 77%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English fȳr, fire — adjectival suffix -y. As a color modifier, fiery implies a saturated-and-bright-flaming quality, the bright color of autumn-foliage fall-color and forge-furnace hot-iron emission. Sits at the bright-and-warm end of the grid, parallel to flaming and blazing in usage.
The genus Hedera, the evergreen climbing vines of European woodland — English ivy, Algerian ivy, Persian ivy — colonizers of stone walls, oak trunks, and any abandoned masonry. The color refers to mature ivy leaves on a south-facing wall: a deep, glossy green with the high specular shine of waxy cuticle. Darker than spinach, cooler than holly, with the architectural association of a plant that wraps human structures back into landscape.
