FWIW the best colour is usually just out from stumble on the way in - I can tell the difference in running between about 9 and 1200 revs, but after that any difference is too small to detect, particularly if you have worked out how the gearbox works and like to keep the motor spinning 500 revs either side of peak torque.
That's great if you set your idle mixture JUST for idling but I don't. Idle mixtures are best set at a compromise leaning towards what gets the engine up off idle the best which is usually a bit rich just for idling. After all, our engines should not idle that much. It's bad for them on a number of different levels.
