Electric Yucatan
Electric Yucatan (#EF64B5) is a true magenta with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (325°, 81%, 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
From the Greek elektron, amber — the substance whose static-electric properties were observed by Thales of Miletus. Used as a color modifier since the late nineteenth century after electric light made certain saturated colors feel attention-demanding. Electric blue, electric pink: the implication is hot luminance combined with optical impact. Sits at the bright-bucket extreme.
Mexican peninsula, the limestone Karst shelf of southern Mexico — home of the Pink Lakes of Las Coloradas (deep magenta saline waters colored by halophilic algae and brine shrimp). Yucatan color refers to a Las Coloradas Pink Lake surface in midday sun: a saturated, slightly cool deep magenta with the matte finish of halophilic-algae-and-brine-shrimp-tinted hyper-saline water. The lakes are also a Phoenicopterus ruber flamingo nesting site.
Closest matches
The nearest named color in three reference sources, ranked by perceptual distance (ΔE76 in CIELAB). ΔE < 1 is imperceptible to most viewers; ΔE > 10 is clearly different. When two sources point to the same hex they’re merged into one tile; click any to open that color’s page.

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.
