Loud Rubellite
Loud Rubellite (#F36656) 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 (6°, 87%, 65%) 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.
Etymology
Old English hlūd, making noise — borrowed metaphorically as a color word since the nineteenth century. Loud red, loud yellow: a color so saturated it announces itself without needing surrounding context. Sits in the bright-bucket extreme alongside electric and striking. Carries a slightly pejorative implication of excess.
A red variety of tourmaline — colored by manganese impurities and mined principally in Brazil, Mozambique, and Madagascar. The color refers to a faceted rubellite: a saturated, slightly cool red-pink with the gem's signature internal warmth. Cooler than ruby, brighter than rhodolite.

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.
