How can I make a blend effect like the one that you get looking through a red glass? Thanxxxxxxxxxxx

i was just reading about that, it goes something like this:
(er..this is probably for 2d but hopefully can spark anidea)

     glEnable (GL_BLEND); glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glShadeModel (GL_FLAT); glClearColor (0.0, 0.0, 0.0, 0.0); drawscene(); glColor4f(1.0, 0.0, 0.0, 0.5); //color for red glass drawglass()  

it''''s all about a good time!
