The main difference between Seafoam and Pistachio is hue — Seafoam is a cool-leaning teal, while Pistachio is a cool-leaning green. Seafoam and Pistachio are often confused but have distinct differences in hue, saturation, and tone. Seafoam (#71EEB8) and Pistachio (#93C572) 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.
Seafoam is more saturated (79% HSL vs 42%) so it reads as bolder and more memorable at logo scale, while Pistachio can feel washed out when printed small.
Pistachio hits a 2.01:1 WCAG contrast against white — safer for text-heavy interfaces — where Seafoam only reaches 1.44:1 and risks failing AA at small body sizes.
Seafoam is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Pistachio leans cooler and is better suited to autumn/winter layering.
Pistachio is the more muted of the two (42% saturation) and sits more calmly on large wall surfaces, while Seafoam's higher chroma can overwhelm a room when used beyond accent pieces.
Seafoam (#71EEB8) is a light, vivid teal with a cool-leaning undertone — it feels airy, soft, approachable and bright, energetic, eye-catching.
Pistachio (#93C572) is a light, moderately saturated green 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.
