Change the color of GUILayout.Box text?

Currently my Summary text is black, which does not look good in the inspector, I’d like it like white for example. This is for my custom inspector script. I tried adding GUILayout.Color.white which didn’t work.

GUILayout.Box("Summary", GUILayout.ExpandWidth(true));

class SomeMonoBehaviour : MonoBehaviour
{

    GUIStyle boxStyle;

    void OnGUI()
    {

        if(boxStyle == null)
        {

            boxStyle = new GUIStyle(GUI.skin.box)
            boxStyle.normal.textColor = Color.white;

        }

    }

}

You might have to set boxStyle.hover/focused.textColor or such as well
