The main difference between Seafoam and Mint is hue — Seafoam is a cool-leaning teal, while Mint is a cool-leaning green. Seafoam (#93E9BE) is a pale blue-green named after ocean foam, while Mint (#98FF98) is a pale green with almost no blue. Seafoam leans cooler and more teal; mint is pure cool green.
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.
Seafoam (RGB 147,233,190) is a soft, pale blue-green with noticeable blue content — named after the pale green-blue of ocean foam. Reads as coastal, soft, and fresh.
Mint (RGB 152,255,152) is a pale pure green with minimal blue, named after fresh mint leaves. Reads as crisp, cool, and minty.
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.
