Poised Cardinalflower

#b3170b
Notes

Poised Cardinalflower (#B3170B) is a true 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 (4°, 88%, 37%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

adjective

Old French peser, to weigh — past-participle of poise. As a color modifier, poised implies a saturated-and-balanced-and-confident quality where the hue holds its position with elegant equilibrium. Sits at the bold-and-confident end of the grid, parallel to centered and composed.

Cardinalflower
noun

Lobelia cardinalis, the North American wildflower whose tall spikes of brilliant red flowers are the favored nectar source of ruby-throated hummingbirds in late summer.
