Hot Nasturtium
Hot Nasturtium (#E97438) is a true orange with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (20°, 80%, 57%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English hāt, of high temperature — applied metaphorically to color since the eighteenth century for warm hues at high saturation. Hot pink, hot red: the implication is luminous intensity combined with thermal warmth. Sits in the bright-and-warm corner of the grid, alongside burning and vivid.
Tropaeolum majus, the South American climbing plant naturalized as a kitchen-garden flower across Europe. Nasturtium (from the Latin naris-torquere, nose-twisting, for the peppery flavor) has edible leaves and saturated red-orange flowers. The color refers to a fresh T. majus bloom: a saturated, slightly red orange with the satin finish of bee-pollinated flower. Brighter than carrot.

How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
