Colour codes.

[Graham_Wright]

I have always assumed that they run 0,1,2.3,4,5,6.7,8, .9..

I've just received cable tags with white labelled 1 and 9, sort of pink.

Are there two standards?

 

[Skipper_Christoph]

Are you refering to the color codes of resistors?
I don't think this standard is applicable for cable markers.

I've now ordered these;-

That's the norm, although the Ebay listing does show what they sent you. Can't see it matters if you're just labeling your boat wiring.

The correct numbering helps in referencing the circuit diagram.

I'm intrigued by the possibility of two standards.

our sticky tag dispenser is the same code as your OP, and although we use numbered cable we still tag our standard loom parts for quick colour reference when fitting. For one off looms for customers who want simplicity to reference, we use different coloured cables.
Another thing we do for our modular engine looms is use different coloured heat shrink for each electrical component.

Anyone brave enough to post the mnemonic?

An ex-RAF engineer freind (sadly now no longer with us) told me this one was in common usage in RAF.

There are many many colour codes for numbers (not necessarily base 10 either)
blacK, browN, Red, Orange, Yellow, Green, Blue, Violet, Slate, White is just one (note the capitalised letter in each, which is the standard single letter abbreviation)
Pink features in some military spec which is adopted by Phirrips.
UK telecoms have 2 x 5 colour sequences, line pairs are made of one wire from each sequence: individually identifying hot and cold of 25 pairs.
Some systems utilise stripes, dots and dashes of one colour over another. I had an old pinball machine wired thus with fun looms containing:
white
white with black stripe
white with black dots
white with black dashes
black with white dashes
black with white dots
black with white stripe
solid black.....
that were a real giggle to fix.

Single letter is quicker and sufficient if its your day job.

that's pretty much brit standard for wiring diagrams for the last few decades, those tiny letters I cant read anymore alongside the schematic
