To ensure the pink color contrasts well with the vibrant green ( #10a573 ), I’ve selected a brighter, more vivid pink that will stand out against it. Here’s the updated palette:

1. Main Color: #10a573 (a vibrant green).
2. Darker Dusty Green: #4B8A6D (a muted, darker green).
3. Bright Contrasting Pink: #FF1F68 (a bright pink that contrasts well with the green).
4. Sand Color: #D4C29A (a soft sand color).
