Authoritative Juno Amaranth
Authoritative Juno Amaranth (#F43B65) 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 (346°, 89%, 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

The genus Amaranthus — the grain crop and ornamental flower whose deep red-purple flower spikes give the color its name. Cultivated by the Aztecs as a ceremonial grain. The color refers to a fresh amaranth flower at peak bloom: a saturated, slightly cool deep red-purple with the matte finish of densely packed small flowers. Cooler than burgundy, warmer than wine.
