Heavy Bellflower
Heavy Bellflower (#343193) is a true blue with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (242°, 50%, 38%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
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.
The genus Campanula — Latin for little bell — small to mid-sized perennials whose bell-shaped blue or violet flowers fill rock gardens and herbaceous borders across temperate climates. The color refers to a fresh Campanula medium canterbury bell: a saturated, slightly violet-shifted blue with the matte finish of a single bell-form flower. Cooler than periwinkle, warmer than larkspur, with the cottage-garden weight of a plant that names an entire genus and color.
