Senatorial Tempranillo

#b52634
Notes

Senatorial Tempranillo (#B52634) 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°, 65%, 43%) 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

Senatorial
adjective

Latin senātōrius, of the senator — adjectival suffix. As a color modifier, senatorial implies a saturated-and-aristocratic-and-Roman-Republic quality, the deep-rich color of Roman-Senate toga praetexta purple-bordered ceremonial-citizen-class livery. Sits at the bold-and-aristocratic end of the grid, parallel to patrician and imperial.

Tempranillo
noun

The dominant red grape of Rioja and other Iberian wine regions — early-ripening (temprano meaning early) and characteristically saturated. The color refers to a young Tempranillo in a glass: a saturated, slightly cool deep red with the optical clarity of mid-to-high-tannin wine. Deeper than Merlot, warmer than Sangiovese.

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.
