Here’s an updated color palette with a greyish taupe, along with sage green and orange:

{
  "palette_name": "Sage and Sunset",
  "colors": [
    {
      "name": "Sage Green",
      "hex_code": "
                            
                            #B2C8B2
                        "
    },
    {
      "name": "Vibrant Orange",
      "hex_code": "
                            
                            #FF6F30
                        "
    },
    {
      "name": "Grey Taupe",
      "hex_code": "
                            
                            #A49A8D
                        "
    }
  ]
}

In this revised palette, the taupe has a more greyish tone, providing a softer and more muted contrast to the vibrant orange and soothing sage green.
