Aqueous Amazon
Aqueous Amazon (#98AC97) is a true green 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 (117°, 11%, 63%) places it in the muted 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin aquōsus, full of water — adjectival suffix -ous. As a color modifier, aqueous implies a pale-and-water-thin-and-translucent quality, the pale color of Japanese-sumi-e and Chinese-Song-dynasty-painting heavy-water-dilution ink-painting surface-finish. Sits at the pale-and-diluted end of the grid, parallel to watery and thinned in usage.
The largest river basin and rainforest on Earth — and the unifying deep green of Amazonian canopy seen from above. Amazon color refers to the average reflectance of an unbroken Amazon canopy: a saturated, slightly cool deep yellow-green with the matte finish of high-rainfall tropical foliage.

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.
This color sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
