Hi Alessandra,

Here is a suggestion:

1: Change the type of the gray image to a color image, that should
make the input to your plugin a ColorProcessor.
2: ColorProcessor has a method: setColor(java.awt.Color color), use
that to set the color.
3: ImageProcessor / ColorProcessor has a drawOval(int x, int y, int
width, int height), use that to draw the circle, by setting width =
height.
4: Save the image.
