I go through intermittent phases of needing use the resistor colour code and tend to forget it -or at least start to doubt my recollection of it- between times. So I have it written out on a piece of paper that sits inside my hobby box of odd resistors. I have normal colour vision, yet between the fact that the coloured bands are tiny, often dirty, and badly printed, it is often easier to get the multimeter out.
It occurs to me that it should -between digital photography, and clever software that can identify objects and colours- be possible to take a photo and have the colour codes read automatically.
cheers
