Realtime Color Filtering/Subtractive Material for BGE

You know that in the game engine there are 6 options for 'Alpha Blend' for a material, they are: Alpha Anti-aliasing, Alpha Sort, Alpha Blend, Alpha Clip, Add and Opaque. I want in a addition to this great selection, Subtract. This would basically filter the color of the material away (or for a more user-friendly interface it could filter the negative of the material color) from the scene behind it allowing colored-glass-like effects, coloring the scene without hazing it out as the current options do. Could this also work with a textured material? If you don't understand what I want please comment your queries. Thanks
