The main difference between Green and Viridian is hue — Green is a cool-leaning green, while Viridian is a cool-leaning teal. Green and Viridian are often confused but have distinct differences in hue, saturation, and tone. Green (#008000) and Viridian (#40826D) each suit different design contexts — understanding their differences helps you choose the right color for your project.
Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Green is more saturated (100% HSL vs 34%) so it reads as bolder and more memorable at logo scale, while Viridian can feel washed out when printed small.
Green hits a 5.14:1 WCAG contrast against white — safer for text-heavy interfaces — where Viridian only reaches 4.53:1 and risks failing AA at small body sizes.
Viridian is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Green leans cooler and is better suited to autumn/winter layering.
Viridian is the more muted of the two (34% saturation) and sits more calmly on large wall surfaces, while Green's higher chroma can overwhelm a room when used beyond accent pieces.
Green (#008000) is a dark, vivid green with a cool-leaning undertone — it feels rich, serious, substantial and bright, energetic, eye-catching.
Viridian (#40826D) is a dark, muted teal with a cool-leaning undertone — it feels rich, serious, substantial and subdued, sophisticated.
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.
