                            #ffaaaa
                        "
    },
    {
      "name": "Dark Teal",
      "hex_code": "
                            
                            #005555
                        "
    },
    {
      "name": "Bright Green",
      "hex_code": "
                            
                            #55ff55
                        "
    },
    {
      "name": "Teal",
      "hex_code": "
                            
                            #00aaaa
                        "
    }
  ]
}
