6 ga wire colors

I think I read all conductors bigger than 6 are black and color identified for purpose by tape or other means. Can you run 3 conductors of 6 for 220v using all green or all black and cover any portion of the wire exposed by tape to denote its purpose ?
Thanks

No. You could use two black and one #10 green. No need to differentiate between the two blacks.

Note: Nominal voltage is 240 not 220.

Technically.... green and white wires can not be re-marked.
Green is always ground and white is always neutral.

6 ga wire

Could I use 6 ga black as neutral on branch circuit using white tape ? Could I use it as ground on sub panel feed using green tape
Thanks

Only #4 and larger can be remarked another color. If it is a 240 only circuit there is no neutral.

Some, not all, LOCAL inspectors will allow a homeowner to re-identify (use colored tape) on black insulated conductors rather than insist on using the proper insulation color. Ask your local inspector. The National Electrical Code specifies that no conductor smaller than #4 may be re-identified. This rule is because the "code making panel" determined that a contractor (my emphasis) would suffer no hardship having different colors for sizes 6 and smaller.

Remember, the ONLY code you need to adhere to is the LOCAL code enforced in your jurisdiction. The NEC is a "model" code and has no force of law UNTIL it is enacted into law by a state, county or city legislative body. The enabling legislation may add to or delete from the model code as the legislators see fit. Your LOCAL inspector has a fair amount of leeway in determining if YOUR installation is compliant.

Inspector is a no waiver, no exception, no humor kind of guy. Code it is.
Thanks for all the info.
