Authoritative Yamabuki
Authoritative Yamabuki (#F04D1E) 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 (13°, 88%, 53%) 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
Latin auctōritāt-, authority — adjectival suffix -ive. As a color modifier, authoritative implies a saturated-and-formal-imperative quality where the hue carries decisional weight and institutional credibility. Sits at the bold-and-authoritative end of the grid, parallel to commanding and magisterial in usage.
Kerria japonica, the Japanese rose-family shrub whose bright yellow-orange flowers cover steep hillsides in late spring. Yamabuki-iro (mountain-rose color) gave Japanese its name for a saturated yellow-orange hue used in court robes and woodblock prints. The color refers to a fully open kerria flower: a saturated, slightly red-shifted yellow-orange with the satin finish of small five-petaled bloom. Warmer than canary, lighter than marigold.

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.
