Great, it does exactly what I need, see image. (red noteheads are the lowest in score)! 
So on this spot I have to lower the bassline in the left hand of piano.

Hi Eef,

I write mostly arrangements where I bring a melody voice down to the double bass (my instrument :-))

Double bass is written an octave higher then sounding, so a lot of times, the score lookes OK, but in fact there are voice crossings between lefthand of piano and the double bass (what gives unwanted/unpleasant voice crossings.

To check this, I transpose the double bass voice down an octave and manually check the boths voices.

Wonder if there is a function in lilypond to do this fastly. Like the coloured noteheads when checking a voice against the ambitus of an instrument.

This reminds me of a function I wrote last year to automatically colourise the lowest sounding pitch in a score. (In my case, this was for harmonic analysis of canons.) See attached.

Maybe this could be used or at least adapted?
