You can mix just about any transparent color of any value from these five pigments. Lamp black is mostly a cheat; if you’ve already mastered color composition you can mix all but the darkest mute colors from the other four and use them as blacks and greys.
Carlisle United managers who were far more successful after leaving the club.
Ivor Broadis was the youngest ever manager of any team who had been in the Football League at the time (and still holds that record), he went back to playing after he left.

Bob Stokoe returned twice.
Nigel Pearson is a bit of a stretch, It would be hard to be less successful than he was at Carlisle.
