Diaphanous Honeydew
Diaphanous Honeydew (#E9FEF0) is a soft green with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (140°, 91%, 95%) places it in the highly saturated band at a light 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
From the Greek diaphanēs, transparent — used as a color modifier since the seventeenth century for hues with the optical translucency of fine fabric. Diaphanous white, diaphanous pink: very low saturation combined with the optical impression of light passing through. Sits at the pale-bucket alongside sheer.
Old English honeg-dēaw, honey-dew — the pale-cool-pale-gray-and-pale-cream aphid-secreted carbohydrate-rich excrement of late-summer-and-autumn deciduous-tree-foliage, often colonized by Cladosporium sooty-mold fungus. Honeydew color refers to a freshly secreted aphid honeydew drop on a Acer-pseudoplatanus (sycamore) leaf-surface in raking late-summer light: a pale cool gray with the glossy finish of pure-sugar aphid-excreted carbohydrate-rich droplet on a polished-leaf surface.

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.
