Jade

The #00a86b Jade hue maintains a strong 6.8:1 contrast ratio against black, which comfortably meets WCAG AAA standards for readability. This makes it a reliable, high-visibility choice for primary action buttons or essential UI elements that require clear legibility.

Because Jade #00a86b is a balanced, saturated green, it pairs beautifully with charcoal to ground its intensity or cream for a softer, organic aesthetic. For a more vibrant, complementary scheme, consider adding accents of terracotta to introduce a warm, earthy counterpoint.
