Frenetic Karakurenai
Frenetic Karakurenai (#F46D8E) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (345°, 86%, 69%) 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
Greek phrenitikós, frenzied — adjectival suffix -ic, derived from phrēn (mind). As a color modifier, frenetic implies a saturated-and-frenzied-and-active quality, the bright color of Hyper-Color-and-Memphis-Group 1980s-design saturated-and-active visual-rhythm. Sits at the bright-and-active end of the grid, parallel to frantic and manic in usage.
Literally Chinese crimson in Japanese — the deep, saturated red associated with imported Tang-dynasty silks and the Heian-period aristocratic taste for continental luxury. The color refers to a karakurenai-dyed silk preserved in the Imperial Repository at Shōsō-in: a saturated, slightly cool deep red with the matte finish of layered aka-kō dye. Deeper than akane, cooler than vermillion.

Accessibility
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.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
