Pale Congo
Pale Congo (#B1CAB0) is a soft 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 (118°, 20%, 74%) places it in the muted band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. 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
From the Latin pallidus, pale, wan — used as a color modifier since the medieval period for hues that read as low-saturation and high-light. Pale pink, pale yellow: low saturation combined with high lightness. Sits at the pale-bucket center alongside light and soft.
The central African river and basin — and the saturated deep green of Congo Basin rainforest, the world's second-largest tropical-rainforest system after the Amazon. Congo refers to a Congo Basin canopy in the wet season: a saturated, slightly cool deep green with the matte finish of equatorial-rainforest 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.
