PolyStyle color not working in Google Maps

[OahuRE]

It seems the below KML is not working in Google Maps.  No matter what I do it shows the fill as the same color.

 

     <PolyStyle>
        <color>7f00ff00</color>
      </PolyStyle>

 

I have attached the complete file is anyone wants to try it.

OK, I figured it out.  I needed the following:

 

  <Style id="style1">
    <LineStyle>
      <color>40000000</color>
      <width>3</width>
    </LineStyle>
    <PolyStyle>
      <color>73FF0000</color>
      <fill>1</fill>
      <outline>1</outline>
    </PolyStyle>
  </Style>

 

and then I put the following line in the Placemark and now the color can be changed.

 

<styleUrl>#style1</styleUrl>
