glColor3f(1.0, 1.0, 1.0); // color is nice and white
// draw a buncha white stuff
glPushColor(); // save the current color (white)
glColor3f(1.0, 0.0, 0.0); // change color to red
// draw a buncha red stuff
glPopColor(); // restore the previous color
// draw more stuff in white
such thing as glPushColor() ?

I think there was a function that pushed the color but i cant recall the name and i couldnt find it on google. It basically was a useful tool for temporarily storing the color. For example
Does this function exist? what is it called?
Instead of using google, just go straight to the source: opengl.org
Check the gl1.4 spec or this page:
http://www.opengl.org/developers/documentation/man_pages/hardcopy/GL/html/gl/
I don''t think the function you are talking about exists.

I didnt check, but I can guess that might be useful, say you wanted to make everything in the entire scene a little redder, then you could do
glColor3f(0.1,0.0f,0.0f);
glPushColor();
//draw everything in the scene as normal, and whatever colors they want, but a little redder
glColor3f(1.0f,1.0f,1.0f); // actually shows up on screen as 1.1f, 1.0f, 1.0f
glPopColor();
glColor3f(1.0f, 1.0f, 1.0f); // actually shows up as 1.0f, 1.0f, 1.0f
at least thats my idea of how it may be useful to have those commands.
EDIT, at least to my understanding, your example of the Push and Pop commadns is not right, in your example the "red" stuff would actually be 2.0, 1.0, 1.0 (I think)

there is no glPushColor, at least that i know, but for what u are trying to do, use attributes:
glPushAttrib(GL_CURRENT_BIT);
glColor3fv(color);
draw_object();
glPopAttrib();
in this way, the color set between push/pop attrib doesnt affect any other object in ur scene

in ur code, u cant save the white color because the push is after u specify it, u have to do it, before set the color.
there is no glPushColor, at least that i know, but for what u are trying to do, use attributes:
glColor3fv(white); //set color to white
glPushAttrib(GL_CURRENT_BIT);
glColor3fv(blue);
draw_object(); //in blue
glPushAttrib(GL_CURRENT_BIT);
glColor3fv(red);
draw_object(); //in red
glPopAttrib(); pop the red color
draw_object(); //in blue
glPopAttrib(); //pop the blue color, then the color is white
draw_object(); //in white
in this way, the color set between push/pop attrib doesnt affect any other object in ur scene,
