The main difference between Lime and Chartreuse is a subtle hue shift within the green family — the hue angle moves 30° between them, changing the perceived undertone. Lime (#00FF00) and Chartreuse (#7FFF00) 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.
Lime is more saturated (100% HSL vs 100%) so it reads as bolder and more memorable at logo scale, while Chartreuse can feel washed out when printed small.
Lime hits a 1.37:1 WCAG contrast against white — safer for text-heavy interfaces — where Chartreuse only reaches 1.30:1 and risks failing AA at small body sizes.
Lime is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Chartreuse leans cooler and is better suited to autumn/winter layering.
Lime is the more muted of the two (100% saturation) and sits more calmly on large wall surfaces, while Chartreuse's higher chroma can overwhelm a room when used beyond accent pieces.
Lime (#00FF00) is a medium, vivid green with a cool-leaning undertone — it feels balanced, versatile and bright, energetic, eye-catching.
Chartreuse (#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.
