    },
    {
      "name": "Pale Mint",
      "hex_code": "
                            
                            #b7e1d2
                        "
    }
  ]
}

This palette combines the warmth of Warm Sand and the calming effect of Slate Blue, enhanced by the soft touch of Dusty Rose and the freshness of Pale Mint.
