Canopy glass color

Is there anyway to change the color of the canopy glass of aircraft in FS2004? Most of the free downloadable aircraft have really unnnatural blueish or grayish tone of the glass which completely changes the view throught the virtual cockpit and mostly ruins the flying experience. I haven't found any utility allowing to chance this and don't know if it's possible. I'd be happy if it was. Maybe complete removing glass from the canopy would be a solution too. Is there anyway to do this?
Thank you for your additions
