Those are 4 predefined fogs colors and 1 to free use.
Example:
d3d_fogcolor4.red = 255;
d3d_fogcolor4.green = 0;
d3d_fogcolor4.blue = 255;
fog_color = 4;
Purple fog Like Purple Rain... but Deep Purple souds much better YEAH!

fog_color = 1 - fog will be a white distance fog
fog_color = 2 - blue fog.... etc
