A prism
Red and green light. Yellow glass transmits yellow light. Yellow light is a combination of red and green light. Therefore yellow glass transmits red and green light and absorbs blue light.
This is easy to do with a Prism, preferably a long triangular piece of glass. A glass of water can do the same thing, although not as accurate as a triangular shaped prism would.
When light passes through a flat piece of glass, like a window, the light is refracted at both surfaces, but the exiting ray of light is parallel to the entering ray and hence the light's path is not really changed.
A "prism". Note: Prisms actually have five sides. There is no three-sided polyhedron.

This is the same as if you had a light to a piece of glass..... the light is bended.
A glass prism is the best way to see how light can be separated into the full spectrum of color. A cut crystal piece will also break the light up.

the light rays hit the piece of glass and the surface of the glass causes it to refract
That could be a prism, or a lens with a serious chromatic aberration problem.
