Read my previous post and follow the link, the outer sheath grey and white colour code is consistant with pvc and ever since its introduction they are stil available till today, with regards to alluminuim conductors they are still available and often used by DNO this is the confusion you are asking when things were phased out but the examples you give are all still commonly in use; if not domestic then in other parts of the industry.
You've answered your owed query on the core colour code, but can you be more specific
E.g. Domestic, industrial, power and lighting cables, swa, micc........ the make up and scope of cables is extensive over the various area's of the industry and to answer it all would be a massive task in deed.
Please narrow it down if the link wasn't what you were after.. hopefully this isn't homework as we are here to help but not to cheat you through your education.
