Working with Issue Labels
Labels are appended using the method NewIssue.Labels.Add(x).
Example:
var myNewIssue = new NewIssue("Issue with dropdown menu");
myNewIssue.Labels.Add("bug");
The default labels that come with every repository are: - bug - duplicate - enhancement - help wanted - invalid - question - wontfix
A Note on Label Colors
The official API returns colors without the leading # that you may expect when working with hex colors -- for example, white would return FFFFFF, not #FFFFFF.
If you're displaying the colors, you may need to add the # in order to display them properly.
