Notes

Stark Fragola (#631C54) is a deep magenta with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (313°, 56%, 25%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals.

Etymology

Stark
adjective

Old English stearc, stiff / strong — sharing root with German stark and Dutch sterk. As a color modifier, stark implies a deep-and-uncompromising contrast where the hue stands without modulation against its substrate. Sits at the deep-and-formal end of the grid, parallel to severe with sharper visual register.

Fragola
noun

Italian for strawberry (Fragaria × ananassa) — the deep-pink aggregate-fruit cultivated worldwide and the eponymous flavor-base for gelato alla fragola. Fragola color refers to a freshly hulled Fragaria × ananassa aggregate-fruit cross-section: a saturated, slightly cool deep magenta with the matte finish of anthocyanin-rich strawberry-flesh against the pale yellow-green achenes. The Latin fragāria refers to the fragrance of the wild fruit.

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.
