Here are a few ways to leverage the calming and refreshing properties of blue-green in your design:

• Create a tranquil atmosphere. Blue-green excels at creating a sense of peace and serenity. Use it as a background color for calming experiences like meditation apps or spa booking platforms.
• Highlight important elements. Blue-green can stand out without being overwhelming. Use it for call-to-action buttons or primary navigation elements to draw user attention while maintaining a clean aesthetic.
• Evoke nature or growth. The natural world connection of blue-green makes it ideal for eco-friendly brands or interfaces related to plants and wellness.
• Consider contrast. Ensure proper contrast with text or other UI elements for optimal readability. Consider a Figma plug-in to ensure accessibility.Balance with warmer colors. Pairing blue-green with a touch of a warm color like orange or yellow can add vibrancy and prevent the interface from feeling too cold.
