Given that the 110v wiring is running in another compartment and is

From the "common sense" stand point the supply is balanced so there is
not need to identify the phases (like there is in 3 phase) so the same
colour can be used for both. Both are at 55v above earth and yellow is
already associated with 110v "safe" supplies it therefore seems
logical to use two yellows.

The center tap, is that bonded to local earth or floating? If it is
bonded and thus a real protective earth then green/yellow would be
logical. If it's floating hum, well...

It is bonded to earth.

Like you say and Andrew had also suggested, large yellow cables seem
sensible. It isn't even as though phase identification is important
as it is with three phase. Nevertheless, I'll probably connect it
consistently.
