Based on your query, I have created a color palette that features varying shades of grey and brown. Here’s the color palette:

json
{
  "palette_name": "Muted Earthy Tones",
  "colors": [
    {
      "name": "Light Grey",
      "hex_code": "
                            
                            #D3D3D3
                        "
    },
    {
      "name": "Medium Grey",
      "hex_code": "
                            
                            #A9A9A9
                        "
    },
    {
      "name": "Dark Grey",
      "hex_code": "
                            
                            #696969
                        "
    },
    {
      "name": "Brown",
      "hex_code": "
                            
                            #8B4513
                        "
    },
    {
      "name": "Dark Brown",
      "hex_code": "
                            
                            #5B3A29
                        "
    }
  ]
}

This palette features a mix of greys and browns, providing a muted and earthy aesthetic suitable for various design projects.
