The white for neutral, green or green with yellow stripe for ground, 
other colors for hot is an official rule in the NEC, but only for 
permanent wiring. NEC doesn't cover anything "inside the box".

CE stuff has green w/yellow for ground.  Blue and Brown for AC line.  I 
believe that this is an IEC standard.  Since there's no U.S. standard 
for internal wiring, and there IS for CE mark, most things follow the 
IEC standard.

I don't know about low voltage DC though.
