Assured Tempranillo

#a40b30
Notes

Assured Tempranillo (#A40B30) is a deep red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (345°, 87%, 34%) places it in the highly saturated band at a dark 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 teal. 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.
