changing color of inherited fontstring font

[wellbeing]

i just want this text to be gray and at .6 alpha

<FontString name="$parent_Text" inherits="GameFontHighlightSmall" text="EMPTY">
       <Color r=".2" g=".2" b=".2" a=".6"/>
	  <Anchors>
	      <Anchor point="CENTER"/>
	  </Anchors>
						
</FontString>

is it not possible to change the color of an inherited font in xml or am i simply doing it wrong?

the fontstring shows up if i remove the color line. it does not show up with the color line in the code.
