To achieve a lighter and softer pink that contrasts well with the vibrant green ( #10a573 ), I’ve selected a softer shade. Here’s the revised palette:

1. Main Color: #10a573 (a vibrant green).
2. Darker Dusty Green: #4B8A6D (a muted, darker green).
3. Soft Pink: #FF6F91 (a softer, lighter pink that still provides contrast).
4. Sand Color: #D4C29A (a soft sand color).

Here’s the JSON representation of the updated color palette:

This palette now features a gentle pink that complements the vibrant green and maintains a fresh, tropical feel. Would you like to make any further adjustments or explore different combinations?
