Does anyone think it would be useful to mark hex bits somehow to make
it easier to find the right one? In particular a way to find the PZ2
that one always wants would be very handy.

Is there any sort of standard colour coding (I've found a few sets
advertised with colour coding but I can't see any sort of consistency).

I was just thinking of marking my PZ bits with a black stripe for PZ0,
brown for PZ1, red for PZ2 and orange for PZ3. (Think resistor colour
codes, they're embedded in my brain so easy for me). Then maybe a
single colour for all Philips and another for slotted as these are
less frequently used.

Couldn't agree more with the idea.

A number of years ago I painted rings round some of mine. Yellow, cyan, magenta (approximately). Just tedious cleaning them up enough for the paint to stick well. And then doing some more every time I buy any - or find some in another place I hadn't looked.

You've guessed - I just have a few left that have paint rings. And I can't remember what coding system I used.

I really don't understand why some standards haven't emerged.

You can buy them ready coloured.

Just to add my 2p worth: The boxes the bits come in and back to front.
The hex part of the bits is held in the box, with the business end of
the bit on display. So, you grab the bit with your fingers and insert it
into the bit holder.

Turn them round, so the business end is held by the case, and the hex
end sticks up. Then just push the bit holder onto the hex end of the
bit. When finished with the bit, push it back into the box in the
correct position, and release it from the bit holder.

Sounds like a plan. I suspect using the R code is going to be better than whatever colour code some bit makers use. For philips you might use the same basic colours but dilute them.

Its not worth anything like 2p.

The boxes the bits come in and back to front. The hex part of the bits is

and release it from the bit holder.

Trouble with that approach is that the bits would have to be much further
apart so you can get just one into the bit holder. And the hole would have
to be variable for the variable business ends of the bits.

I had a simialr situation with keys so decided to stamp them with a number.
Perhaps hex keys though would be too tough to stamp.

I'd go for coloured heat shrink rather than paint. Maybe red for PZ2 and

Yes I've found by a bit of Googling that in the Bad Boys mnemonics, it's
normally "rape" rather than "ring" ;-)


It had never occurred to me (and I feel a right pillock that it's taken me
nearly 50 years for it to dawn on me) that the order of the colours for
resistors was the same as the order in a spectrum (which I remember as
Richard Of York Gained Battles In Vain) but with black, brown and grey,
white either side of that.

Talking of mnemonics, how about this one for getting spelling of a certain
difficult word correct: Died In A Rolls Royce Having Over-Eaten Again. I
think it was either Gervase Phinn or Jack Sheffield who mentioned it in one
of his books about things that little children say: allegedly one of his
pupils had invented that mnemonic. In the US, the spelling is different so
it would just be Having Eaten Again.

Yes, 'ring' makes no sense at all.

Needless to say, a few years ago, a teacher 'got into trouble' over the
mnemonic.

It had never occurred to me (and I feel a right pillock that it's taken
me nearly 50 years for it to dawn on me) that the order of the colours
for resistors was the same as the order in a spectrum (which I remember

Yes, I realised the spectrum connection, and have never needed a
mnemonic for that - orange looks like it is between red and yellow (as
well as possessing 'oranginess'), &c.

I wonder whether people who work with colour a lot, like artists and
designers 'see' more distinct colours than the six that most (non
colour-blind) 'see', or only if they have extra words for the colours
(like teal and indigo).

At school, when we were doing the spectrum, a colour-blind boy said he
could only see three colours. I think the teacher told him to shut up.

Components are so tiny these days that I often have difficulty telling
orange from red from brown in the tiny bands. And then you have 1% and
2% tolerance resistors so you have to work out which end to start. I
often end up using a multimeter. Life was a lot easier when resistors
were big chunky things with clearly visible bands, or the old "body tip
and dot" ones.

Yes, I have the same problem. I use a jeweller's loupe quite a lot; I can
hold it in my eye for a long time due to practice with the monocle!

I too use a multimeter, also for small value capacitors, because some of
the markings are ambiguous.

It is alleged that women, on average, can determine finer differences
between near-identical colours than men. I've seen tests on web sites where
you are presented with several patches of colour, all of them identical
apart from one which is very slightly different.

I'm not sure whether the ability to see "that dress on the internet"
(https://www.independent.co.uk/news/w...-10074228.html)
as blue or gold is generally polarised men versus women. For the record, I
see it as gold and bluey-white: probably taken in the shade (which tends to
be blueish) on a camera that is set for sunlight. Given that the dress is
supposed to look like this
https://www.independent.co.uk/news/w...-10074553.html,
the photo that divided everyone is a spectacularly bad rendition of it and
I'm not surprised that so many people saw something different!

When I worked in a chemistry lab as a research assistant in my year off
between A levels and university, we were doing a lot of work with adding
tracers to proteins - either radioactive or colour-change. My supervisor
asked me "are you colour blind?", and when I said I wasn't, he told me about
my predecessor who kept getting different colour changes to those reported
in scientific papers. Eventually my supervisor looked over this guy's
shoulder and found that the colour changes were exactly as expected... but
the assistant was reporting them wrongly. "Oh, I'm colour blind - does it
matter?" he asked, innocently. Does it matter - just a little ;-)

Apparently the change in UK wiring colours from Red, Black, Green to Brown,
Blue, Green-and-Yellow (L, N, E) was partly for the benefit of colour blind
electricians: with most forms of colour blindness, the new colours appear
differently to each other, whereas the old colours made live and earth
appear very similar.

I remember hearing a colour blind person saying that he could not
distinguish between red and green traffic lights and had to rely entirely by
position, so he had to be extra careful at night when he couldn't see *at a
distance* whether there were two unlit lights above the one that he could
see was lit, to give context. That's partly why many (all?) traffic lights
now have a white rectangular border around the three-light head so you can
infer the position of the light that you can see.

Speed, the auto-contradicting senile sociopath, blabbered, again:


A fellow student at college invented his own mnemonic which was British
Boys Ride On Your Great Big Virgin Girls With Great Stamina.

That must have been Boris.

Spare everyone your senile attempts at senile "humour", senile idiot!

Does anyone think it would be useful to mark hex bits somehow to make
it easier to find the right one? In particular a way to find the PZ2
that one always wants would be very handy.

Is there any sort of standard colour coding (I've found a few sets
advertised with colour coding but I can't see any sort of consistency).

I was just thinking of marking my PZ bits with a black stripe for PZ0,
brown for PZ1, red for PZ2 and orange for PZ3. (Think resistor colour
codes, they're embedded in my brain so easy for me).

I remember the mnemonic Bye Bye Rosie On You Go Birmingham By Great Western
(or Buy Better Resistors Or Your Grid Bias May Go West - Mauve rather than
Violet). There's also Bad Boys Ring Our Young Girls But Vicky Goes Without
or Bad Boys Ring Our Young Girls But Vicky Gives Willingly (anyone know
Vicky's phone number?)

The difficult part is remember which way the Black and Brown go in the
mnemonic!

very pc compared to the usual mnemonic

I couldn't rememeber the usual mnemonics, I found it easier to rember the colours but one going around my school (perhaps Harry started it) was

Black Boys Rape Our Young Girls But Vrigins Grow Wise.

It's been years since I've seen pink on a resitor IIRC if the last band was pink it meant 20% tolerence.

Just remember it's a spectrum, so starts at black and ends in white.



Golly after years of staring at resistors I dont need no mnemonics

Neither do I, actually. Just offering advice.

Not just resistors, either, or other components. Mainframe circuit boards
numbered with three plastic dots, etc.

those dipped polyxx capacitors that had IIRC red for 250V and yellow for 400V working.

Life was so colourful, now I need a magnifier just to see the surface mount componets.

We get asked to make circuit boards such as.

Please find the attached files for an antenna we would like to fabricate. The design is simple and the holes do not need to be plated. The board thickness is 0.787mm and I will give it to you by today.

Yes I've found by a bit of Googling that in the Bad Boys mnemonics, it's
normally "rape" rather than "ring" ;-)


It had never occurred to me (and I feel a right pillock that it's taken me
nearly 50 years for it to dawn on me) that the order of the colours for
resistors was the same as the order in a spectrum (which I remember as
Richard Of York Gained Battles In Vain) but with black, brown and grey,
white either side of that.

Talking of mnemonics, how about this one for getting spelling of a certain
difficult word correct: Died In A Rolls Royce Having Over-Eaten Again. I
think it was either Gervase Phinn or Jack Sheffield who mentioned it in one
of his books about things that little children say: allegedly one of his
pupils had invented that mnemonic. In the US, the spelling is different so
it would just be Having Eaten Again.

ah, 'dire rear'.

I thought they just had no band for 20%

Now we have LED traffic lights, we should change the red stop to be octagonal.

It is alleged that women, on average, can determine finer differences
between near-identical colours than men. I've seen tests on web sites where
you are presented with several patches of colour, all of them identical
apart from one which is very slightly different.


Shortly before colour TV started we had a very interesting
conversation with our RS rep who revealed that he was colour
blind. However, although he couldn't see colour, he could see
minor variations that normally sight folk can't.

He said that when he visited Ford's factory at Dagenham he
walked past the production line and would often spot a car and
think "I don't know what colour it is but some poor beggar is
going to by a car with different colour doors to the body!"

This was very useful during the war. He was part of an
experiment involving a group of colour blind men and an equal
number with normal sight. The RAF took them on a circular
flight of Britain that took in several camoflaged sites.

He and his group spotted all of them whereas the other group
spotted none!

single colour for all Philips and another for slotted as these are
less frequently used.

I had a simialr situation with keys so decided to stamp them with a number.
Perhaps hex keys though would be too tough to stamp.


I'm puzzled by this thread as all my hex bits (from a number
of sets) are all stamped Pz1, Pz2, Ph1, Ph2 etcetera, so I
don't see the problem.

Also, I always keep them in their holders in groups in
sequence, so I can usually pick the correct one without
needing the markings.

I had heard something similar; where colour blind cards are setup to
catch various groups with certain forms of colour blindness, where a
normally sighted person will not see a number of pattern, but one with
certain kinds of colour blindness will.

I do find it horrifying that there are people out there driving who
can't tell the difference between a green or red light.
