The main difference between Lime and Spring Green is hue — Lime is a cool-leaning green, while Spring Green is a cool-leaning teal. Lime and Spring Green are often confused but have distinct differences in hue, saturation, and tone. Lime (#00FF00) and Spring Green (#00FF7F) 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.
Lime is more saturated (100% HSL vs 100%) so it reads as bolder and more memorable at logo scale, while Spring Green can feel washed out when printed small.
Lime hits a 1.37:1 WCAG contrast against white — safer for text-heavy interfaces — where Spring Green only reaches 1.35:1 and risks failing AA at small body sizes.
Lime is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Spring Green 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 Spring Green'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.
Spring Green (#00FF7F) is a medium, vivid teal 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.
