Bracing Castile
Bracing Castile (#FFD310) is a true amber 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 (49°, 100%, 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old French bracier, to embrace — present-participle of brace. As a color modifier, bracing implies a saturated-and-cool-and-energizing quality, the bright color of Atlantic-Cornish-coast and Hebridean-island fresh-sea-air visual-stimulation. Sits at the bright-and-cool end of the grid, parallel to invigorating and crisp in usage.
The arid central plateau of Spain — and the warm tan of Castilian sandstone and the wheat fields of La Mancha. The color refers to a Castilian meseta in late summer: a soft, slightly muted warm tan-yellow with the matte finish of dry wheat-and-soil landscape. Drier than honey.

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.
