Here's what I know.
The 4 wires going into the six-prong connector on each MOTOR are: yellow, SPACE, brown, red, SPACE, then black (left to right).
Nibs towards me.
Into my Xvico BOARD, they are Black, Brown, Yellow, Red, left to right, nibs away from me.
Phase-wise, on the MOTOR, Yellow and Red are the "left" phase, Brown and Black are the "right" phase.
But the cable end plugging into the motor isn't the decider here.
What matters is what's plugged into my Xvico board, because I'm going to change that connection to work with my Duet Mini 5+.
So, in an attempt to get this right, by meeting Duet's A+A- B+B- paradigm, I'm going to with Yellow-Red, + -, as Phase 1 on the LEFT, and Brown-Black, + -, as Phase 2 on the RIGHT.
Any opinions?

This easy way to find stepper phase. When not connect to any electronics, just in your hand.
Turn the stepper shaft by hand - should turn easy.
Short 2 of the 4 wires and turn the shaft again - still easy NOT a phase / Harder to turn its a phase.
Short the remaining 2 wires - Harder to turn the shaft the other phase.
If you did find the phase the first time try 2 other wires until you do.That's how I've always done it and never killer a driver.

@rushmere3d that's how I figured out what I started this thread with. I used a motor from my old Anet A8 first, but used the X-motor on my Xvico to find out what's what with it.

As long as the two A connections of the Duet go to one coil of the stepper and the two B connections go to the other coil all is good.
I would be consistent using the same color for each connection, whatever those colors may be, for each stepper.
The wire colors, of the printer I am working on currently, are RED, BLUE, GREEN and BLACK but I cannot tell you from memory what colors go with what coil.
And as you know you can determine which two connections on a stepper are for one coil using a meter that will report resistance or continuity.

Never ever trust colors on wires on steppers! Find windings as described earlier.

I know that well.
The proceeding sentence includes "whatever those colors may be". I then went on to provide an example from my steppers which differ from the colors the OP mentioned, reinforcing the fact that there is no standard color scheme for steppers.
Thanks.

Exactly as @fcwilt says. Determine which pairs of wires are phases either using a multimeter or doing the short-a-pair-and-turn test.
The wiring scheme A-NC-B-A-NC-B that you described is one of the two schemes I have come across on motors with 6 pin connectors.
