The main difference between Jade and Emerald is hue — Jade is a cool-leaning teal, while Emerald is a cool-leaning green. Jade (#00A86B) and Emerald (#50C878) are similar colors often confused. They differ in brightness, saturation, and undertone, making each better suited for different design contexts.
Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Jade is more saturated (100% HSL vs 52%) so it reads as bolder and more memorable at logo scale, while Emerald can feel washed out when printed small.
Jade hits a 3.08:1 WCAG contrast against white — safer for text-heavy interfaces — where Emerald only reaches 2.13:1 and risks failing AA at small body sizes.
Emerald is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Jade leans cooler and is better suited to autumn/winter layering.
Emerald is the more muted of the two (52% saturation) and sits more calmly on large wall surfaces, while Jade's higher chroma can overwhelm a room when used beyond accent pieces.
Jade (#00A86B) is a dark, vivid teal with a cool-leaning undertone — it feels rich, serious, substantial and bright, energetic, eye-catching.
Emerald (#50C878) is a medium, moderately saturated green with a cool-leaning undertone — it feels balanced, versatile and balanced in intensity.
Text legibility depends on the contrast ratio between foreground and background. WCAG 2.1 AA requires at least 4.5:1 for normal text and 3:1 for large text; AAA requires 7:1. Use these numbers to choose accessible combinations for your design.
