When light passes through a piece of red glass, it selectively absorbs all colors except red. Therefore, the light that reflects off the piece of red glass will only be yellow-white. However, since the light is reflecting off of two surfaces (the front and back of the glass), two images will be formed. One image will be yellow-white since it is the color of the reflected light, and the other image will be red since it is the color of the glass. So, one image is yellow-white and the other is red.
