The main difference between Kelly Green and Hunter Green is brightness and saturation: both are green shades, but Kelly Green is lighter and Kelly Green is more saturated. Kelly Green and Hunter Green are often confused but have distinct differences in hue, saturation, and tone. Kelly Green (#4CBB17) and Hunter Green (#355E3B) 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.
Kelly Green is more saturated (78% HSL vs 28%) so it reads as bolder and more memorable at logo scale, while Hunter Green can feel washed out when printed small.
Hunter Green hits a 7.46:1 WCAG contrast against white — safer for text-heavy interfaces — where Kelly Green only reaches 2.49:1 and risks failing AA at small body sizes.
Kelly Green is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Hunter Green leans cooler and is better suited to autumn/winter layering.
Hunter Green is the more muted of the two (28% saturation) and sits more calmly on large wall surfaces, while Kelly Green's higher chroma can overwhelm a room when used beyond accent pieces.
Kelly Green (#4CBB17) is a medium, vivid green with a cool-leaning undertone — it feels balanced, versatile and bright, energetic, eye-catching.
Hunter Green (#355E3B) is a dark, muted green 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.
