Pulsating Pineapple
Pulsating Pineapple (#C9E649) is a true yellow with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (71°, 76%, 59%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin pulsātio, beating — present-participle of pulsate, sharing root with pellere (to drive). As a color modifier, pulsating implies a saturated-and-beating-and-rhythmic quality, the bright color of rave-and-festival light-show synchronized-pulse rhythmic-emission. Sits at the bright-and-active end of the grid, parallel to throbbing and strobing in usage.
Ananas comosus, the cultivated pineapple — domesticated in the Caribbean and South America by the Tupí and a luxury good of seventeenth-century European glasshouses, where a single fruit could cost the equivalent of thousands of dollars. The color refers to a ripe pineapple's flesh: a clean, slightly translucent gold-yellow that's brighter than honey and softer than canary, with the optical brightness of high-water-content tropical fruit.

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.
