Hi,  I'm trying to use a display list to draw a set of axes in 3D, the code for the display list is below, but for some reason the colors aren't showing up (everything is gray) - I needed the x, y, and z axes to be red, green, and blue respectively.  Any ideas as to why these colors aren't rendering?

Thanks!

1. void createAxesList(){
2. if(!(boolean)gl.glIsEnabled(gl.GL_NORMALIZE)) gl.glEnable(gl.GL_NORMALIZE){
3.       axesList = gl.glGenLists(1);
4.        gl.glNewList(axesList, gl.GL_COMPILE);
   
    
      //x axis
     gl.glColor3f(1.0f, 0.0f, 0.0f);
     gl.glBegin(gl.GL_LINES);
     gl.glVertex3f(0.0f, 0.0f, 0.0f);
     gl.glVertex3f(80.0f, 0.0f, 0.0f);
     gl.glEnd();
5. 
     //y axis
     gl.glColor3f(0.0f, 1.0f, 0.0f);
     gl.glBegin(gl.GL_LINES);
     gl.glVertex3f(0.0f, 0.0f, 0.0f);
     gl.glVertex3f(0.0f, 80.0f, 0.0f);
     gl.glEnd();
6. 
     //z axis
      gl.glColor3f(0.0f, 0.0f, 1.0f);
     gl.glBegin(gl.GL_LINES);
     gl.glVertex3f(0.0f, 0.0f, 0.0f);
     gl.glVertex3f(0.0f, 0.0f,80.0f);
     gl.glEnd();
    
     gl.glEndList();
   
   }
