The main difference between Mint and Seafoam is hue — Mint is a cool-leaning green, while Seafoam is a cool-leaning teal. Mint (#98FB98) and Seafoam (#93E9BE) 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.
Mint is more saturated (93% HSL vs 66%) so it reads as bolder and more memorable at logo scale, while Seafoam can feel washed out when printed small.
Seafoam hits a 1.43:1 WCAG contrast against white — safer for text-heavy interfaces — where Mint only reaches 1.27:1 and risks failing AA at small body sizes.
Mint is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Seafoam leans cooler and is better suited to autumn/winter layering.
Seafoam is the more muted of the two (66% saturation) and sits more calmly on large wall surfaces, while Mint's higher chroma can overwhelm a room when used beyond accent pieces.
Mint (#98FB98) is a light, vivid green with a cool-leaning undertone — it feels airy, soft, approachable and bright, energetic, eye-catching.
Seafoam (#93E9BE) is a light, moderately saturated teal with a cool-leaning undertone — it feels airy, soft, approachable 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.
