Glowing Day Eucalyptus
Glowing Day Eucalyptus (#2DCEA0) 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 (163°, 64%, 49%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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
The progressive participle of glow, to emit light — used as a color word since the medieval period for hues that read as if they were luminous from within. Glowing amber, glowing rose: the implication is moderate saturation combined with the optical impression of internal light. Sits in the bright-bucket alongside radiant.
Old English dæg, daylight period. As a color modifier, day implies a midday-and-broad-daylight quality, the visual register of Mediterranean-and-temperate mid-day full-sun atmospheric clarity-and-shadow open-sky working-and-walking surfaces under noon-day overhead light. Sits at the modifier-and-time end of the grid, parallel to noon and morn in usage.
The genus Eucalyptus, the gum trees that dominate the Australian forest canopy and have been planted across the world for fast-growth timber and the menthol-camphor oil. The color refers to mature eucalyptus leaves with their pale waxy bloom: a soft, slightly muted blue-green with the matte finish of cuticle that reflects more light than typical foliage. Cooler than sage, warmer than mint.

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.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
