there is one inconsistency on those calls
List Labels return the color without #
but Create Label requires the #
it's not a big deal but it is kinda boring for someone who uses it
Because then you get errors like this:
panic: Error creating label [Affects Agent e11d21 This will require a new release of TrustFactor agents]: 422 Unprocessable Entity: [{"fieldNames":["Color"],"classification":"SizeError","message":"Size"}]

posible solution: display issueCreateLabel example without '#' and make it pars version with and without '#' on the beginning

Actually I was kinda thinking about appending the # to the List Labels response

Parsing it regardless of # sounds reasonable to me.
