  // rgb: [255, 0, 0],
  // hex: "#ff0000",

  // appearance
  wheelDiameter: 200,
  wheelThickness: 20,
  handleDiameter: 16,
  wheelReflectsSaturation: true,

  // handler
  onChange: function (color) {
    // the only argument is the ReinventedColorWheel instance itself.
    // console.log("hsv:", color.hsv[0], color.hsv[1], color.hsv[2]);
  },
});

// set color in HSV / HSL / RGB / HEX
colorWheel.hsv = [240, 100, 100];
colorWheel.hsl = [120, 100, 50];
colorWheel.rgb = [255, 128, 64];
colorWheel.hex = '#888888';

// get color in HSV / HSL / RGB / HEX
console.log("hsv:", colorWheel.hsv[0], colorWheel.hsv[1], colorWheel.hsv[2]);
console.log("hsl:", colorWheel.hsl[0], colorWheel.hsl[1], colorWheel.hsl[2]);
console.log("rgb:", colorWheel.rgb[0], colorWheel.rgb[1], colorWheel.rgb[2]);
