Strobing Cataract
Strobing Cataract (#3BE9E3) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (178°, 80%, 57%) 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
Greek stróbos, whirling — present-participle of strobe. As a color modifier, strobing implies a saturated-and-pulse-flashing quality, the bright color of concert-strobe-light and photographic-strobe high-frequency-pulse light emission. Sits at the bright-and-flashing end of the grid, parallel to flashing and pulsating in usage.
A large waterfall with significant volume — particularly the Cataracts of the Nile and the Iguaçu Cataract of South America. Cataract color refers to the deep blue-white of high-volume falling water at Iguaçu: a saturated, slightly cool deep blue-white with the optical brightness of micron-scale air-water mixing.

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.
