In the latest version (5.3.12) released today, there is at least metapost attribute you can use to color splay shots.

Just redefine l_survey_cave symbol in layout, e.g. 50% gray like this:

code metapost
  def l_survey_cave (expr P) =
    T:=identity;
    pickup PenC;
    if ATTR__shotflag_splay:
      thdraw P withcolor (0.5,0.5,0.5);
    else:
      thdraw P;
    fi;
  enddef;
endcode

I agree with Marco about the colour of splays in different colours than the
legs. How can we achieve this?
