Note: This class is NOT in the default HashTables returned by HSSFColor. The index is a special case which is interpreted in the various setXXXColor calls. 

 public HSSFColor() 
{

}

Creates a new instance of HSSFColor

 public String getHexString() 
{
        return BLACK.hexString;
}

 public short getIndex() 
{
        return BLACK.index;
}

 public static final Hashtable getIndexHash() 
{
        return createColorsByIndexMap();
}

this function returns all colors in a hastable. Its not implemented as a static member/staticly initialized because that would be dirty in a server environment as it is intended. This means you'll eat the time it takes to create it once per request but you will not hold onto it if you have none of those requests.

 public short[] getTriplet() 
{
        return BLACK.triplet;
}

 public static final Hashtable getTripletHash() 
{
        return createColorsByHexStringMap();
}
