Here’s the revised color palette that keeps the forest green, goldenrod, and charcoal gray while introducing new greens:

{
  "palette_name": "Green and Gold Fusion",
  "colors": [
    {
      "name": "Forest Green",
      "hex_code": "
                            
                            #228B22
                        "
    },
    {
      "name": "Olive Green",
      "hex_code": "
                            
                            #808000
                        "
    },
    {
      "name": "Seafoam Green",
      "hex_code": "
                            
                            #2E8B57
                        "
    },
    {
      "name": "Vivid Magenta",
      "hex_code": "
                            
                            #D5006D
                        "
    },
    {
      "name": "Goldenrod",
      "hex_code": "
                            
                            #DAA520
                        "
    },
    {
      "name": "Charcoal Gray",
      "hex_code": "
                            
                            #36454F
                        "
    }
  ]
}

In this palette, mint green and lime green have been replaced with olive green and seafoam green, both providing a richer and more earthy feel while complementing the existing colors.
