Flat Trumpetvine
Flat Trumpetvine (#883623) is a deep red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (11°, 59%, 34%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old Norse flatr, flat / level. As a color modifier, flat implies a clear-and-evenly-spread quality where the hue carries the matte-finish visual register of unmodulated single-plane surface. Sits at the crisp-and-balanced end of the grid, parallel to level and even in usage.
Campsis radicans, the North American climbing vine whose bright orange-red trumpet flowers attract ruby-throated hummingbirds. The color refers to a fresh trumpetvine bloom in midsummer: a saturated, slightly red orange with the satin finish of long tubular flower. Brighter than nasturtium, warmer than tangerine.
