Weighty Trumpetvine

#ad3f23
Notes

Weighty Trumpetvine (#AD3F23) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (12°, 66%, 41%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Weighty
adjective

Old English wegan, to weigh — adjectival suffix -y. As a color modifier, weighty implies a saturated-and-heavy-and-imposing quality where the hue carries visual mass and gravitational presence. Sits at the bold-and-weighty end of the grid, parallel to substantial and hefty in usage.

Trumpetvine
noun

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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
