Resonant Raspberry

#ac1c4b
Notes

Resonant Raspberry (#AC1C4B) is a true 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 (340°, 72%, 39%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Resonant
adjective

Latin resonāns, echoing — present-participle of resonate, sharing root with sonance. As a color modifier, resonant implies a saturated-and-deep-vibrating quality where the hue carries low-frequency visual richness. Sits at the bold-and-resonant end of the grid, parallel to sonorous and resounding in usage.

Raspberry
noun

Rubus idaeus, the European raspberry — its name traces to Mount Ida in either Crete or Anatolia, where the fruit was first described in classical literature. The color refers to a ripe raspberry's drupelets: a saturated, slightly cool deep red-pink with the optical complexity of a hundred-cell aggregate fruit. Cooler than coral, warmer than fuchsia, with the orchard-and-jam weight of a fruit whose color is identical to the food-coloring industry's raspberry red.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

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.
