I think it's more sexist than racist tbh.

I just look up the free card that I got with Practical Electronics in 1973 or thereabouts......

If you have an android phone, you can download ElectroDroid from Android Market. This has Resistor Colour code banding calculator on it plus lots of other fun stuff! I can't think of any reason that I would need to use it now since I don't work with electronics anymore but it's better than my big fold-out Farnell poster.

This is the one my ole dad taught me years ago and he's a chartered engineer.

Bad Boys Rape Our Young Girls But Virgins Go Without.

None! i just know them..

there are some things such as this and particularly concerning music that it's best just to know.
Using Mnemonics just adds a further stage and slows down the process.
But you need to be practising and using the info on a regular basis for that to work of course.

We were taught the so called "racist" version back in 81, although the lecturer was quick to point out that it could cause issues for some people so we were probably better off replacing the first word with "bad".

Yes.....the racist one back in the 60's, but what the hell, you don't quote it out loud do you? It's remembering that's important.

Actually, used regularly, you stop seeing colours after awhile, and see them as numbers anyway.
Good for wire colours too, as you colour code wires in numerical sequence when you have lots. Exceed 10, and you have multi coloured wires. i.e. black seies with tracer colour (red /orange/yellow etc) first, brown series with tracer colour next: no more wire tracking needed, you can go to either end without thinking about it.

One of out lecturers always ended his lesson with the saying "It doesn't matter how you remember/achieve, so long as it works and is safe is all that matters" - and he was right IMO.

As far as choice of words go, I believe it's not what is said - but the context it is used in that determines whether it is offensive/racist/etc.

Search Youtube for "Many uses of F word" for a perfect example of context. Some people will no doubt be offended, but it's bang on the money and quite amusing at the same time when you realise just how true it is.

The way my brain works (mostly doesn't work ) is that I can't remember mnemonics - it's easier for me just to remember Black, Brown (colours of the rainbow except indigo) Grey, White

As Birkee said up-thread, after a while you just see the numbers anyway.

Body tip dot anyone?

Agreed, and especially when they come in only certain combinations in an E12 or occasionally E24 series, so you'd get used to brown-green or orange-orange or yellow-violet as the first two, and the next was usually one of only about half the series
