Electrifying Mekong
Electrifying Mekong (#3199F8) is a true azure 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 (209°, 93%, 58%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Greek ēléktron, amber — present-participle of electrify, named after the static-electricity property of rubbed amber. As a color modifier, electrifying implies a saturated-and-shocking-and-active quality, the bright color of Tesla-coil high-voltage atmospheric-discharge emission. Sits at the bright-and-active end of the grid, parallel to charged and neon in usage.
The Southeast Asian river flowing from the Tibetan Plateau through China, Burma, Laos, Thailand, Cambodia, and Vietnam. Mekong color refers to mid-depth Mekong River water at Luang Prabang in Laos: a saturated, slightly cool deep blue-brown with the optical complexity of monsoon-fed silty river water.

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.
