Overhead Projectors

I don’t know want to use them on Overhead Projectors. I need it to change the color of light for a science project. I need blue, green, and red. Purple is okay too instead of blue.

I know there’s a Michaels and AC Moore where I live. There’s Office Depot and Staples, as well. Help?
