Electric Aquamarine
Electric Aquamarine (#5DF5D2) is a true teal 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 (166°, 88%, 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 red. 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.
An iron-tinged variety of beryl — the gemstone mined from pegmatite veins in Brazil, Madagascar, and the Pakistani Karakoram. Named for the Latin aqua marina, seawater. The color refers to a faceted Santa Maria aquamarine: a clean, slightly green-shifted blue with the gem's high refractive brilliance. Lighter than sapphire, deeper than seafoam, with the gem-trade specificity of a stone graded primarily for color depth.
