In my experiance over the years cable colour codes seem to be a bigger issue although there is a standard hardly any one uses it or they have there own preference.
BS 7645:1993, IEC 60757:1983 is the standard for colour codes.
This standard implements CENELEC Harmonized Document, HD 457 S1, so I suppose if you choose not to follow it, and someone in the EU makes a mistake and gets hurt as a result of non-standard colour designations on a wiring diagrams, not sure where it would go.
Would recommend if you don't follow this standard, then ensure the key is on every sheet of the diagram, and VERY visible.
BS EN61082-1 is the general standard for laying out circuit diagrams.
