Torrid Stream
Torrid Stream (#3DE7F8) is a true cyan 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 (185°, 93%, 61%) 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
Latin torridus, parched / scorching — sharing root with torrēre (to dry by heat). As a color modifier, torrid implies a saturated-and-tropical-hot quality, the bright color of equatorial-Saharan-and-Sonoran-desert mid-summer high-temperature surface-emission. Sits at the bright-and-warm end of the grid, parallel to scorching and fiery in usage.
A narrow flowing body of fresh water — smaller than a river, larger than a creek. The color refers to a clear stream over a gravel bed in temperate woodland: a soft, slightly green-shifted blue with the optical clarity of unsilted water. Cooler than aqua, lighter than tide, with the hydrological weight of a word that appears across nearly every English landscape vocabulary.

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.
