Will my 3D glasses work with clear cellophane?

I have to make 3d glasses for science and I found out how and it said that I needed blue cellophane and red cellophane but I could only find clear cellophane so will it still make everything look 3d if I stuck blue and red colours on top of the clear cellophane?Will my 3D glasses work with clear cellophane?
Red/blue glasses will not make everything look 3d. They only work for pictures that are specially printed with red and blue inks. See this article for some examples and for an explanation of why it works:

Clear cellophane won't work. The color is important. In a nutshell, the idea is that two pictures are printed in the same frame, one with red ink and one with blue ink. The red celophane traditionally goes over your left eye. It makes the red image invisible, so that your left eye only sees what was printed in the blue ink. The blue cellophane makes the blue image invisible, so your right eye only sees what was printed in red ink.





Stereo vision is possible because your two eyes see a scene from slightly different angles. Stereo photography is done with a camera that has two lenses, that each see the scene from two slightly different angles. When the left-hand picture is presented to your left eye and the right-hand image is presented to your right eye, then you will see the scene the same way that the camera saw it, in 3D.
