Sometime you may have a switching requirement where you have a white wire you want to use as a "Hot" connection. Depending on your local inspector you can often get away by using black electrical tape at each end of the circuit to indicate it is a "Hot" wire. On new construction this wouldn't typically be accepted.

12ga wire is 12ga wire,the color is used to indicate what it is.
House wire is romex, so you have the color already inside.
For the most part, wire that is run in conduit is single strand and does not have a sheathing.
Ex- I buy a 500ft spool of thhn/thhw- I do not buy a spool of black,red,white,green.
I only buy black,and color code all other wires.
I wrap the other ends with red,white,green, electric tape,and and inch below the top wrap with another wrap, to indicate that the wire is used for hot,neutral and ground.
As the person said above,about new, but anyway,when dealing with romex,there is no reason you should have to use a different color, unless you have say 12/2wgr but needed 12/3wgr, do not run a single strand with the rest to make up for the missing wire.
Some switches are installed as a break,that is, hot does not run to switch, there is only one set of wire(12/2wgr) from switch to fixture, so the hot goes to light box, but then runs to switch then back to light, so inside the box or fixture I connect the black to black then the white coming up from switch,wrap with black tape and attach to light because it is now a hot wire.

Is neutral wire same size as hot in 200 amp panel?
Yes, in a residential 200 amp panel, the neutral wire is typically the same size as the hot wires. This is to ensure that the neutral wire can safely carry the same current as the hot wires and maintain proper balance in the electrical system. Always consult the National Electrical Code or a qualified electrician for specific requirements.
