<extrude> kml tag - how to control color and opacity?

[radek]

Hi all,

When using <extrude> and <altitudeMode> tags in kml, like in example
from reference:

<Placemark>
<name>extruded</name>
<LineString>
<extrude>1</extrude>
<tessellate>1</tessellate>
<altitudeMode>relativeToGround</altitudeMode>
<coordinates>
-122.364167,37.824787,50 -122.363917,37.824423,50
</coordinates>
</LineString>
</Placemark>

you get grey, opaque shape under your feature.

Is there a way of controling colour and opacity of this grey area?

This will give you yellow lines with green walls:

<Style id="yellowLineGreenPoly">
<LineStyle>
<color>7f00ffff</color>
<width>4</width>
</LineStyle>
<PolyStyle>
<color>7f00ff00</color>
</PolyStyle>
</Style>
<Placemark>
<name>Absolute Extruded</name>
<description>Transparent green wall with yellow outlines</
