colored glass effect

How can I make a material that looks and acts like colored glass? For example if I made a cube with a red colored glass and put it on a plane with an image of newspaper it would look like a colored cube of glass and magnify and reflect the image on the newspaper?

Turn on ray-trans for the glass cube and set the IOR value to about 1.5. Make sure ray tracing is enabled before you render.

I tried doing that including changing the alpha to 0.2 but still nothing.

I made some things with colored glass just a few days ago.
