Firm Raspberry

#b31a4e
Notes

Firm Raspberry (#B31A4E) 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 (340°, 75%, 40%) 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

Firm
adjective

Latin firmus, strong / stable — sharing root with English farm (originally a fixed-yearly-rental). As a color modifier, firm implies a saturated-and-resolute quality where the hue holds its visual position without wavering. Sits at the bold-and-firm end of the grid, parallel to steadfast and unwavering 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.
