Could someone please explain when to use brown, orange, yellow and blue,red, black? Orange is supposed to be for the wild leg, correct? I mostly do residential but I am getting into 3 phase. Where does the wild leg come in and if a phase is orange does that mean it is a wild leg? Please help.
After you check out all the threads keep this in mind ... we (the electricians) invented BK/RD/BL, not the NEC. Nothing in the NEC says you can't use pink, purple and mauve. Yes, the orange is mandated for a hi leg.

Actually Steve, almost any color may be used for the high Ø. The verbiage says “orange in color or by other effective means”, the other effective means may be purple, blue, red, or almost any other color as long as it’s the same throughout the plant.
A word of caution. Gray was used as a phase conductor until this cycle, “natural gray” was reserved for the grounded conductor. Just because it is gray doesn’t automatically mean that it is a grounded conductor and it is at ground potential.
Along those same lines, red has been used in this area for the high Ø in a lot of buildings. Additionally, other colors may be used for that particular identification.
The bottom line for both of these statements, “don’t assume!" Use the proper testing procedures along with the lock out, tag out procedures. Remember, go home in the same shape that you went to work in so your kids will recognize you.
As Charlie mentioned, ya gotta be wary of color codes.... San Fran' CA high legs are Purple, in direct contradiction to NEC. But I often find RED "B", and BLUE "Hi-C"(Which seemed to live a short life in the 60's), and of course ORANGE from "Out-of-towners", and PURPLE. On occasion all of the above. So every 3 phase panel to me is in question, and gets the meter. Then it gets the giant magic marker on the panel cover, with whatever leg is high in a big triangle. Lets me know I've been there....
