Marking Single Phase Wiring
I know you can't mark/id anything smaller than 4AWG when phasing..
However, for single phasing, can I just buy a spool of 500 feet....and mark ID red and white , on 8 AWG wire ?

“200.6 Means of Identifying Grounded Conductors.
(A) Sizes 6 AWG or Smaller. An insulated grounded conductor of 6 AWG or smaller shall be identified by one of the following means:
(1)
A continuous white outer finish.
(2)
A continuous gray outer finish.
(3)
Three continuous white or gray stripes along the conductor's entire length on other than green insulation.

Best to ask your LOCAL inspector. Some inspectors will absolutely demand that you use different colors while some will allow a HOMEOWNER to re-identify smaller conductors. No inspector will allow a professional electrician to re-identify smaller than #4 conductors.
The reason for the break at #4 conductors is that the code-making panel decided that it was not a hardship to require an electrical contractor to use the proper colors since they would be able to use the remainder of the spool on a different job and also because wire of #4 and larger is generally not available with different insulation colors. It IS important to re-identify the conductors at ALL points of access such as conduit bodies and pull boxes regardless of any actual connections in these areas.
