    {

    {
      "name": "Slate Gray",
      "hex_code": "

       "
    },
    {
      "name": "Burnt Umber",
      "hex_code": "
          
          #7C4D3A
       "
    },
    {
      "name": "Purple Haze",
      "hex_code": "
          
          #9B59B6
       "
    }
  ]
}

This palette now features “Purple Haze” to represent the flowers, while still including earthy tones that enhance the overall theme. The colors are distinct enough for clarity on a line graph.
