[HELP] Image <colordiffuse> problems

I have some mpaa rating images that I am trying to display in PM3.HD and they are coming in too grey. I have been trying <colordiffuse>white</colordiffuse>, but nothing seems to happen. I have
white in my default.xml in the color folder. Here is my image code...

<control type="image">
<posx>1090</posx>
<posy>615</posy>
<width>166</width>
<height>38</height>
<colordiffuse>white</colordiffuse>
<texture>r.png</texture>
<visible>substring(listitem.mpaa,Rated R)</visible>
</control>

Is there something I am missing or is it just that my image can't be altered within the skin? I would appreciate any help on this. Image I am using and screenshot below.
