Assured Tempranillo

#b73637
Notes

Assured Tempranillo (#B73637) is a true red 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 (360°, 54%, 46%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Assured
adjective

Old French aseürer, to give assurance — past-participle of assure. As a color modifier, assured implies a saturated-and-confident quality where the hue carries unwavering certainty about its own visual identity. Sits at the bold-and-confident end of the grid, parallel to certain and poised.

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.
