Colour codes
In these days of tiny surface mount devices, colour codes are not used as much as they were when I first started in electronics.
They still exist on some parts (through hole and MELF devices for instance) but in the usual surface mount packages they just have a numeric code; unfortunately the manufacturers do not have a standard way of putting those numbers on them.
The easiest follows the original (digit 1, digit 2, multiplier and sometimes with a digit 3) but others have their own way of doing it, which can be a royal pain when trying to find if an incorrect part was loaded.
