color codes of fixed wires in home wiring

Standard wire colours for FLEXIBLE cable (e.g. Extension cords, power (line) cords and lamp cords)
Region or Country	Phases	Neutral	Protective earth/ground
European Union (EU), Australia, South Africa (IEC 60446)	brown	blue	green/yellow
Australia, New Zealand (AS/NZS 3000:2007 3.8.3)	brown, red	light blue, black	green/yellow
Brazil	yellow, red	blue	green
United States, Canada	black (brass)	white (silver)	green (green)
Standard wire colours for FIXED cable (e.g. In-, On-, or Behind-the-wall wiring cables)

European Union (EU) (IEC 60446) including UK from 31 March 2004	brown, black, grey	blue	green/yellow
UK prior to 31 March 2004	red, yellow, blue	black	green/yellow green (formerly) bare conductor, sleeved at terminations (formerly)
Australia, New Zealand (AS/NZS 3000:2007 clause 3.8.1, table 3.4)	Any colour other than green, yellow, green/yellow, black, or light blue Recommended: red or brown for single phase; or red, white or dark blue for multiphase	black or light blue	green/yellow (since about 1980) green (since about 1980) bare conductor, sleeved at terminations (formerly)

Canada	red, black (120/208/240V) red, black, blue (600/347V) orange, brown (single phase isolated systems) orange, brown, yellow (three phase isolated systems)	white (120/208/240V) white (600/347V)	green (green) bare conductor green (isolated ground)
Notes: Parenthesized colours in italics are used on metallic terminals. "Green/yellow" means green with yellow stripe. See illustrations nearby. The colours in this table represent the most common and preferred standard colours for wiring; however others may be in use, especially in older installations. Australian and New Zealand wiring standards allow both European and Australian colour codes. Australian-standard phase colours conflict with IEC 60446 colours, where IEC-60446 supported neutral colour (blue) is an allowed phase colour in the Australia/New Zealand standard. Care must be taken when determining system used in existing wiring. Canadian and American wiring practices are very similar, with ongoing harmonization efforts.
