But turtle.pencolor() returns a tuple of floats, so calling turtle.fillcolor(turtle.pencolor()). This issue shows up in the doctest at library/turtle.rst line 936. I can submit a patch with tests once the tests in bpo-21916 are in.

_color_triple_to_hexstring() is implementation detail. It would be better to test it indirectly using public method (like fillcolor()). Added other comments on Rietveld.
