Prismatic Sangiovese

#fb4b31
Notes

Prismatic Sangiovese (#FB4B31) is a true red with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (8°, 96%, 59%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Prismatic
adjective

Greek prísma, prism — adjectival suffix -ic. As a color modifier, prismatic implies a saturated-and-multi-spectrum-decomposed quality, the bright color of crystal-prism and cut-glass-chandelier light-refraction-spectrum decomposition. Sits at the bright-and-shifting end of the grid, parallel to iridescent and spectral in usage.

Sangiovese
noun

The dominant red grape of central Italy — backbone of Chianti, Brunello, and Vino Nobile. The color refers to a young Brunello di Montalcino: a saturated, slightly cool deep red with the optical complexity of well-aged Tuscan wine. Deeper than Chianti, cooler than Tempranillo.

WCAG contrast

The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.

Wide gamut

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.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
