                        "
    },
    {
      "name": "Sky Blue",
      "hex_code": "
                            
                            #87CEEB
                        "
    },
    {
      "name": "Lavender",
      "hex_code": "
                            
                            #E6E6FA
                        "
    }
  ]
}

This revised palette maintains the cheerful essence of a garden party while incorporating a softer pastel green for a more delicate touch.
