[Solved]-How to change the color of the each slice in piechart based on the backend response using highcharts-Highcharts

you can define slice color on a data level:

  series: [{
    data: [{
        name: "success",
        y: 29.9,
        color: 'green'
      },
      {
        name: "error",
        y: 71.5,
        color: 'red'
      },
      {
        name: "info",
        y: 106.4,
        color: 'orange'
      }
    ]
  }]
