Solid Vermiglione

#b81d2d
Notes

Solid Vermiglione (#B81D2D) 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 (354°, 73%, 42%) 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

Solid
adjective

Latin solidus, firm, dense — used as a color modifier since the seventeenth century for hues that read as continuous and unbroken: a solid blue is one with no variation across the surface. Implies high saturation combined with optical density. Sits in the bold-bucket alongside strong and robust, slightly more focused on uniformity.

Vermiglione
noun

The Italian name for vermillion — used in the cinnabar-pigment chapters of Cennino Cennini's Il Libro dell'Arte and across Sienese and Florentine fresco. The color refers to vermiglione in a fifteenth-century altarpiece: a saturated, slightly orange red with the matte finish of egg-tempera-bound pigment. The Italian equivalent of bermellón.

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.
