The main difference between Turquoise and Mint is hue — Turquoise is a cool-leaning teal, while Mint is a cool-leaning green. Turquoise (#40E0D0) is a vivid blue-green named after the gemstone, while Mint (#98FF98) is a light, cool green named after mint leaves. Turquoise leans blue-green; mint leans pure green with a hint of cool.
Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Mint is more saturated (100% HSL vs 72%) so it reads as bolder and more memorable at logo scale, while Turquoise can feel washed out when printed small.
Turquoise hits a 1.64:1 WCAG contrast against white — safer for text-heavy interfaces — where Mint only reaches 1.23:1 and risks failing AA at small body sizes.
Mint is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Turquoise leans cooler and is better suited to autumn/winter layering.
Turquoise is the more muted of the two (72% saturation) and sits more calmly on large wall surfaces, while Mint's higher chroma can overwhelm a room when used beyond accent pieces.
Turquoise (RGB 64,224,208) is a saturated blue-green that sits on the blue side of the green/blue boundary, famously used in Persian, Egyptian, and Native American jewelry.
Mint (RGB 152,255,152) is a light pastel green with a cool blue undertone, popular in spa, dental, and clean-beauty branding. It reads as fresh, crisp, and minty-cold.
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.
