Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Mint Green is more saturated (93% HSL vs 61%) so it reads as bolder and more memorable at logo scale, while Forest Green can feel washed out when printed small.
Forest Green hits a 4.39:1 WCAG contrast against white — safer for text-heavy interfaces — where Mint Green only reaches 1.27:1 and risks failing AA at small body sizes.
Mint Green is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Forest Green leans cooler and is better suited to autumn/winter layering.
Forest Green is the more muted of the two (61% saturation) and sits more calmly on large wall surfaces, while Mint Green's higher chroma can overwhelm a room when used beyond accent pieces.
Mint Green (#98FB98) is a light, vivid green with a cool-leaning undertone — it feels airy, soft, approachable and bright, energetic, eye-catching.
Forest Green (#228B22) is a dark, moderately saturated green with a cool-leaning undertone — it feels rich, serious, substantial 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.
