Question : to draw a image using red or green color

I need to draw an image. The image is any geometrical shape like square, circle. Currently I am able to draw these shapes using black color. Now I need to give an option to the user, to draw the image using green or red color. The user would be able to select between green or red color. If he selects green, then he should be able to draw the image using green color else, he would be able to draw the image using red color.

Kindly advise how to do it.
