White Wire with Color Tape to Identify Conductors

I am making up a ten foot Liquid tight 3/4" conduit assembly. It will carry three #6 awg conductors for a 240 vac feed. I have a piece of #6 awg THHN white wire that is 40' long. Is it allowable to apply black and red electrical tape at the ends of the conductors to designate that there is a black, a red and a white conductor within the conduuit assembly?
Thanks

No. Not only is it a white wire, it is too small. Only conductors larger than 6 AWG may be redesignated in the field.

Sorry 'bout that.

The good news is that I have one of the three wires that I need. Guess I need to get some black and red for the project.
Thanks

You do not need a white for 240v. You can use two blacks.

Black, red and green, or 2 blacks and a green, or two reds and a green. An A/C condensing unit, if that's what you're supplying, does not require a neutral.

Save the white wire for another job.

The green can be a #10, it doesn't need to be full sized.

Before I buy the wire,
I plan to use a red and a black #6 AWG and a green #10 AWG. Should I go with a #8 or #6 green or is that a dumb idea?

Not a problem, just more expensive.

Not dumb, but more money than you need to spend.

Yep, good call.
