Buzzing Chì
Buzzing Chì (#F6597C) 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 (347°, 90%, 66%) 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
The progressive participle of buzz — borrowed metaphorically as a color word since the late twentieth century for hues that read as visually loud and slightly destabilizing. Buzzing yellow, buzzing magenta: the implication is saturation pushed past comfortable into the realm of optical agitation. Sits at the bright-bucket extreme alongside electric.
One of the five primary Chinese cardinal colors (chì — red — corresponding to the south, summer, and the phoenix). Distinct from hong, which is more general; chì implies the deeper, slightly more saturated red of historical imperial regalia. The color refers to chì-pigment in classical Chinese painting: a saturated, slightly cool deep red with the matte finish of mineral-and-binder pigment.

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.
This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
