      Very cool. This was something most electronic technicians memorized when I was doing that job in the 1970s and 1980s. I do not recall any of this, now. I think when surface mount and multi-layer boards appeared toward the end of the 1980s this was no longer helpful, if that was all you worked on.

      Big Boys Race Our Young Girls But Violet Generally Wins...vaguely remember the resistor saying. I'll have to look..probably a few similar charts in dad's old workshop.
