Short answer..... no.
The JAMMA "pinout" is the code.

Besides, "JAMMA" doesn't even have 6 buttons per player.

Fair Enough

Never, ever, ever rely on wire colours ... even for something ridiculously standardized like PC power cables (would be a ---smurfette--- if that yellow wire didn't actually run 12V, wouldn't it ?).

Yeah, I learned many, many years ago with many different things I have worked on that there are only certain criteria that permits use of color/colour code. (i.e. factory harnesses with factory schematics) And even then I ALWAYS still trace and meter wires. I have seen many a schematic be wrong, especially with color codes.

Anything aftermarket is up in the air to the manufacturers discretion. (i.e JAMMA harnesses, power supplies, etc) Some things may be similar, but not close enough for me to trust them as "standards" or "code".

Fair points. I dont actually have a jamma loom. I was going to wire my CP to the same colour as the jamma colour code. If there is no colour code, I will just wire it to how I want.

There was an AAMA standard wiring color code that AAMA members used for a while.  It required a fair number of colors and also used striped wires.  It wasn't really something suitable for hobbyist use as you won't want to buy that many spools of wire.  It also was by no means a universal standard.  Only a few US arcade game manufacturers (notably Midway) followed it, and the Japanese made up their own standards.

I ---steaming pile of meadow muffin--- you not, but I have a PC PSU where the "standard" black, red, yellow wiring scheme was inverted. IIRC, red/yellow was grounded and the black pair was 12V and 5V. By this time, I was so used to thinking of black as the common that it was irritating the ---fudgesicle--- out of me every time I worked inside that PC. My brain kept wanting me to grab the pliers and rip the pins out of the molex connectors and rearrange them.

At first I tried to tape a Post-It inside the case to remind me the PSU was backasswards. But it just irritated me even more.

I finally found a good excuse when an intermittent break in the harness prompted me to just replace the PSU entirely.

To this day, I wonder if the idiot who assembled it was color blind or something. I can't visualize wiring the loom and keeping track of which black was supposed to go to which voltage. I'm damn fortunate I didn't have any problems beyond the intermittent connection. That PSU is now lost in a box with the other crappy components, like the Compaq proprietary PSU, the junk HDD that no Linux distro will ever mount properly, and those crummy sticks of nickel plated RAM no one ever had any use for.
