Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Lawn Green is more saturated (100% HSL vs 100%) so it reads as bolder and more memorable at logo scale, while Chartreuse Green can feel washed out when printed small.
Lawn Green hits a 1.33:1 WCAG contrast against white — safer for text-heavy interfaces — where Chartreuse Green only reaches 1.30:1 and risks failing AA at small body sizes.
Chartreuse Green is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Lawn Green leans cooler and is better suited to autumn/winter layering.
Lawn Green is the more muted of the two (100% saturation) and sits more calmly on large wall surfaces, while Chartreuse Green's higher chroma can overwhelm a room when used beyond accent pieces.
Lawn Green (#7CFC00) is a medium, vivid green with a cool-leaning undertone — it feels balanced, versatile and bright, energetic, eye-catching.
Chartreuse Green (#7FFF00) is a medium, vivid green with a cool-leaning undertone — it feels balanced, versatile and bright, energetic, eye-catching.
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.
