Quads Lose Color

I have some quads with solid colors laid out flat in my game.  If I disable the lightState like so


Then you can see them fine with their colors.  If however, I enable it and add in some lights (I took these from an example) like so

        SpotLight sp1 = new SpotLight();
        sp1.setDiffuse(new ColorRGBA(0.0f, 1.0f, 0.0f, 1.0f));
        sp1.setAmbient(new ColorRGBA(0.5f, 0.5f, 0.5f, 1.0f));
        sp1.setDirection(new Vector3f(60, 0, 100));
        sp1.setLocation(new Vector3f(60, 30, 100));
        SpotLight sp2 = new SpotLight();
        sp2.setDiffuse(new ColorRGBA(1.0f, 0.0f, 0.0f, 1.0f));
        sp2.setAmbient(new ColorRGBA(0.5f, 0.5f, 0.5f, 1.0f));
        sp2.setDirection(new Vector3f(1, -0.5f, 0));
        sp2.setLocation(new Vector3f(-25, 10, 0));
        DirectionalLight dr = new DirectionalLight();
        dr.setDiffuse(new ColorRGBA(1.0f, 1.0f, 1.0f, 1.0f));
        dr.setAmbient(new ColorRGBA(0.5f, 0.5f, 0.5f, 1.0f));
        dr.setSpecular(new ColorRGBA(1.0f, 0.0f, 0.0f, 1.0f));
        dr.setDirection(new Vector3f(50, 0 , -100));


Then all my quads become the same color gray.  I also have some textured models in the scene and the lights work fine on them.  How do I get the quads to work with the lighting?  Also, my quads are rotated 90 degrees, I'm not sure if that helps at all.

If you use vertex coloring or default color, the lighting calculations will ignore this unless you add a MaterialState that has Color material set (often to Diffuse or Diffuse+Ambient)
