title: Changing tooltip color in Chart.js
body: <p>trying to customized the tooltip based on the value of the data. Also there are these small circular connectors or joins on the corner of a line chart, when the line goes up or down,  that I am also trying to change its color and for those I don't even know where to start. Here is a portion of the code I am using where I am trying to return and change the tooltip color using Chart.js</p>
  
  <pre><code>        tooltips: {
            mode: 'index',
            intersect: false,
            callbacks: {
  
              label: function(tooltipItem, data) {
                if (tooltipItem.yLabel === 1) {
  
      //return 'Normal';
              return { 'Normal',
               tooltipFillColor: 'rgb(255, 99, 132)', // red
          };
  
                } else if (tooltipItem.yLabel === 2) {
  
                 // return 'Active';
          return { 'Acitve',
               tooltipFillColor: 'rgb(75, 192, 192)', // green
          };
  
                }
              }
            }
          },
  </code></pre>
  
  <p>Thanks for all the help!</p>
