How can I color a PrefixLabel?

My question is that simple: I just want to be able to use EditorGUILayout.PrefixLabel but change the text color to white.

A fiew things I tried so far:

 var old = EditorStyles.label.normal.textColor;
 EditorStyles.label.normal.textColor = Color.white;
 EditorGUILayout.PrefixLabel("label Text");
 EditorStyles.label.normal.textColor = old;

 var old = EditorStyles.label.normal.textColor;
 EditorStyles.label.normal.textColor = Color.white;
 EditorGUILayout.PrefixLabel("label Text", new GUIStyle(EditorStyles.label));
 EditorStyles.label.normal.textColor = old;

 EditorGUILayout.PrefixLabel("label Text", new GUIStyle(EditorStyles.whiteLabel));

 var old = GUI.contentColor;
 EditorStyles.label.normal.textColor = Color.white;
 EditorGUILayout.PrefixLabel("label Text");
 GUI.contentColor = old;

 var old = GUI.skin.label.normal.textColor;
 GUI.skin.label.normal.textColor = Color.white;
 EditorGUILayout.PrefixLabel("label Text");
 GUI.skin.label.normal.textColor = old;

 whiteTextStyle= new GUIStyle(EditorStyles.label) { 
     normal = { 
         textColor = TEXT_COLOR_SELECTED 
     } 
 };
 EditorGUILayout.PrefixLabel("label Text", whiteTextStyle);

But so far I have no luck. I can easely change the color of all other elements but for the PrefixLabel nothing is working. I want to stick with PrefixLabel since it simply is less code to have all labels and fields arranged well.

Any hint what else I can try?
