Hi There,

I am trying to show a colored quad on the 2D screen with the following code:

glColor3f(1.0f, 1.0f, 1.0f);

glBegin(GL_QUADS);
glVertex2f(300, 500); // vertex 1
glVertex2f(300, 300); // vertex 2
glVertex2f(600, 300); // vertex 3
glVertex2f(600, 500); // vertex 4
glEnd();

glColor3f(1.0f, 1.0f, 1.0f); // If I don't put this, the whole screen become the previous color

Normally I would expect it to be full white, but I get an 50% gray. Is something with the blend function? Any clues what might be the problem?

Thanks
