If you want to produce multiple log entries, you can use a foreach loop or similar construct to split your list into one-line entries, and write each to the log by calling the WriteToLog() method once per entry.
Using "blank" as the color (or the shorthand overload of the WriteToLog() method that omits the color parameter entirely) can help to visually group a list of items after another item (that does have a colored icon in front of it), if that's something you're looking to do.
