Your plugin can set the color, type and size of the point, or set of points, before adding it to the ROI Manager. The following JavaScript example adds two sets of points to a hidden ROI Manager. Each set of points has a different color, type and size.

  hybrid=0; crosshair=1; dot=2; circle=3;
  tiny=0; small=1; medium=2; large=3; xlarge=4;
  hidden = true;
  rm = new RoiManager(hidden);
  poly = new Polygon();
  poly.addPoint(50,50);
  poly.addPoint(100,100);
  poly.addPoint(200,200);
  points1 = new PointRoi(poly);
  points1.setStrokeColor(Color.yellow);
  points1.setPointType(dot);
  points1.setSize(large);
  rm.addRoi(points1);
  poly = new Polygon();
  poly.addPoint(150,400);
  poly.addPoint(270,270);
  poly.addPoint(400,150);
  points2 = new PointRoi(poly);
  points2.setStrokeColor(Color.cyan);
  points2.setPointType(hybrid);
  points2.setSize(xlarge);
  rm.addRoi(points2);
  img = IJ.createImage("Untitled", "8-bit black", 500, 500, 1);
  img.show();
  for (i=0; i<5; i++) {
     rm.select(0);
     IJ.wait(1000);
     rm.select(1);
     IJ.wait(1000);
 }
