For a darker background while maintaining the warm green theme, here’s a revised palette with a darker background color:

json
{
  "palette_name": "Deep Green Warmth",
  "colors": [
    {
      "name": "Forest Green",
      "hex_code": "
                            
                            #3A6A3D
                        "
    },
    {
      "name": "Warm Olive",
      "hex_code": "
                            
                            #AFAF3A
                        "
    },
    {
      "name": "Moss Green",
      "hex_code": "
                            
                            #6F8B3D
                        "
    },
    {
      "name": "Muted Mint",
      "hex_code": "
                            
                            #A8D9C2
                        "
    },
    {
      "name": "Dark Charcoal",
      "hex_code": "
                            
                            #2C2C2C
                        "
    }
  ]
}

In this updated palette, the “Dark Charcoal” ( #2C2C2C ) serves as a darker background color. It provides a strong contrast to the warmer greens while still maintaining a cozy and inviting atmosphere.
