Heavy Strawberry

#a31b4b
Notes

Heavy Strawberry (#A31B4B) is a true magenta with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (339°, 72%, 37%) 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

Heavy
adjective

Old English hefig, weighty — cognate with heave. Used as a color modifier since at least the seventeenth century to indicate weight in saturation as much as value: heavy with pigment, heavy-bodied. In the engine's adjective grid, heavy sits alongside deep and plush in the dark-and-saturated quadrant. Closer to a fabric description than a pure value word.

Strawberry
noun

Fragaria × ananassa, the cultivated strawberry of European gardens since the eighteenth century. The color refers to the surface of a ripe berry: a clean, bright red with a slight blue shift in the shadows of the achenes. Warmer than ruby, lighter than crimson, with the optical brightness of fresh fruit rather than the depth of pigment or gem.
