Incandescent Porpora
Incandescent Porpora (#EC5169) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (351°, 80%, 62%) 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.
Etymology
Latin incandēscēns, growing-hot — present-participle of incandēscere, sharing root with candere (to shine). As a color modifier, incandescent implies a saturated-and-glowing-hot quality, the bright color of tungsten-filament-glow incandescent-lamp light. Sits at the bright-and-warm end of the grid, parallel to glowing and blazing in usage.
The Italian word for the imperial purple of Roman tradition — derived from murex shells but borrowed in modern Italian color vocabulary for a deep, slightly red-shifted purple-red. The color refers to porpora-dyed Venetian silk: a saturated, slightly cool deep red-purple with the satin finish of plant-and-shell dye. Cooler than crimson, warmer than burgundy.

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.
