Once you receive the response for "get_circles" I want you to use "change_circle" to modify one or multiple circle properties to accomplish our mutual goal. Every time I ask you ask you to do something you should call "get_circles" then "change_circle" after evaluating the response.
The circles blend additively using screen mode, so if I ask you mix colors, you can make the color by moving circles to the same position to blend their colors.
