      "hex_code": "
                            
                            #1E3A8A
                        "
    },
    {
      "name": "Soft Gray",
      "hex_code": "

                        "
    },
    {
      "name": "Warm White",
      "hex_code": "
                            
                            #FFFFFF
                        "
    },
    {
