See Appendix 7 of BS 7671:2008, IEE Wiring Regulations, 17th edition. Table 7E gives Positive (earthed) Blue, negative Grey as 'new colours'. The 'old colours' were Positive (earthed) Black, negative Blue. Potential for confusion infinite! The relevant Europe-wide documents are: HD 308 S2:2001 (harmonized document, not a standard) BS EN 60445:2000 (marking of terminals) BS EN 60446:2000 (colours or markings of cables) -- OOO - Own Opinions Only.
