I suppose it's a bug, although I honestly don't know what the
expected behaviour would be.  If you start a contour series with
a fixed linetype then it auto-increments line types (colors) for
successive contour levels, right?  But if you start it off with
an arbitrary color, as you did with 'lc rgb "#foo"', then how
should it determine the color of the next contour level?

If what you want is to have all contours the same color, 
then the obvious syntax would be something like
    set contour samecolor

although surely there must be a better keyword.
