Colored Description Bubbles in KML for Google Earth
In the new Discovery Channel National Parks placemark collection I noticed they had colored description bubbles in Google Earth. So, I set out to figure out how they did it in the KML. It turns out you need the following KML tags added to a placemark KML file:
- <Style> - name a style type using the "id" parameter
- <BalloonStyle> - start a style for the Balloon
- <color> - specify a color
- <StyleURL> - specify the Style for a specific balloon.
You need the corresponding closing tag for each of the tags above. Read the documentation on KML here.
You can see an example placemark 
I placed in the big blue ocean, and here's the source (the important parts are highlighted in the color red):
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.0">

<Style id="bigblue">
<BalloonStyle>
<color>ffa56a</color>
</BalloonStyle>
</Style>
<Placemark>
<name>The Ocean</name>
<description>This is the big blue Atlantic Ocean.</description>

<styleUrl>#bigblue</styleUrl>
<Point id="khPoint715">

</Point>
</Placemark>
</Document>
</kml>
