     <p>
     Track color for all subtracks in a collection can be set by double-clicking the collection 
     folder in the right window of the Track Collection Builder, which will display a pop-up dialog 
     box. In the pop-up, a color can be set for the subtracks in the collection. Color will be 
     applied as a gradient to subtracks in the collection (e.g., if red is selected, the 
     subtrack graphs will appear in varied shades of red within the browser window).</p>
     <p>
     To revert back to the original track color, change the color picker to '#000000'. To change the 
     track color to black rather than any non-black original color, set the color picker to any shade 
     of black besides '#000000', such as '#000001'. For example, if a track's original color is

 <h3>Step 5: Saving and sharing collections</h3>
 <p>
 Collections will be available 48 hours before expiring. You must 
 <a href="../goldenPath/help/hgSessionHelp.html#Create" target="_blank">save your session</a> to 
 preserve collections long-term and to allow
