blue colors on all graphs

The following change will generate charts "shades of light  blue"
      var defaultColors = [
          //'steelBlue',
          //'rgb(255,153,0)',
          //'rgb(220,57,18)',
          //'rgb(70,132,238)',
          //'rgb(73,66,204)',
          //'rgb(0,128,0)'
              'rgb(0, 169, 221)',
              'steelBlue',
              'rgb(0, 169, 221)',
              'rgb(50, 205, 252)',
              'rgb(70,132,238)',
              'rgb(0, 169, 221)',
              'rgb(5, 150, 194)',
              'rgb(50, 183, 224)',
              'steelBlue',
              'rgb(2, 185, 241)',
               'rgb(0, 169, 221)',
              'steelBlue',
              'rgb(0, 169, 221)',
              'rgb(50, 205, 252)',
              'rgb(70,132,238)',
              'rgb(0, 169, 221)',
              'rgb(5, 150, 194)',
              'rgb(50, 183, 224)',
              'steelBlue',
              'rgb(2, 185, 241)'
      ];

also the following formula will create "pastel" colors

      function pastelColors() {
          var r = (Math.round(Math.random() * 127) + 127).toString(16);
          var g = (Math.round(Math.random() * 127) + 127).toString(16);
          var b = (Math.round(Math.random() * 127) + 127).toString(16);
          return '#' + r + g + b;
      }
