Question: I have installed central air and I no longer need to 220v
window AC outlets.

They are wired with romax and the colors of the conductor insulation
are Black, Red, and White.
With the current cost of copper, I hate to replace these runs.

Standard color codes are of course black, white, copper/gnd. If I
rewire this for 110v what colors should I put where? I read somewhere
in the code that you can re-identify a cable with colored tape (green
for instance for the wire used for ground)

So, should I use black-hot white-neutral and red-green taped at each
end for ground? Does this meet NEC code or at least come close??

Yes, you'll be fine. Make sure the green is continuous and no red is
visible. Isn't there an equipment grounding conductor in the box now?

Unfortunately, no there is no bare or green conductor.

I'm talking from the perspective of absolutely strict code compliance
from the perspective of an anal inspector:

Legally, you can't use a black or red wire as neutral, but you
can use white for hot (with suitable marking). You can't use
any of them as ground, nor can you use a bare ground for anything
else.

How exactly could using a red as a ground hurt anything?
The absolute worst senerio is that someone in the future will be working on
the circuit and find the red isn't hot like he expected, and that the ground
is missing. If he isn't bright enough to put the two together (and the
green tape has fallen off the red wire) he will have to fall back on your
suggestion, but there is no way any harm can result.
