Colour Coding Of Cores
The colour coding of cores of insulated power cables for nominal voltages Uo/U to 0.6/1 kV is specified in the standard DIN VDE 0293 in accordance with the CENELEC harmonization documents.
Cables
For Internal Wiring
With nominal current Uo/U to 300/500 V. Recommended colours for marking the insulated jackets :
black, blue, brown, grey, orange, pink, red, turquoise, violet, white.
All two-colour combinations of the above-mentioned individual colours are permissible. It is only permissible to use the individual colours green and yellow in the manner allowed under the pertinent safety regulations.
Green is permitted to identify lighting chains.
Multiple-Core
Flexible Cables
(2-5 Adern)

3-to-5 core cables without green/yellow cores are currently not included in the harmonized types.
Multiple-Core
Flexible Cables
(> 6 cores)
The green/yellow core is always located in the outer layer. Cores are numbered from the inside beginning at 1. In the case of flat, flexible cables, the green/yellow core is located in the centre if possible.

Single-Core
Sheathed Cables
Insulating jacket of the core : Black or green/yellow. Exception in the case of decorative and lighting chain cable with brown core.
Single-Core
Cables
With nominal voltage Uo/U to 450/750 V. Recommended colours for following single-core coding :
Black, blue, brown, grey, orange, pink, red, turquoise, violet, white.
Use of two-colour combinations other than green/yellow, and the individual colours green and yellow is not permitted for installations due to possible of confusion.
(Observation of the safety standards for equipment and system due to possibly limiting stipulations)
New colour abbreviations have been defined in the CENELEC harmonization document HD 457 for use when ordering single-core cables.
