What are some examples of design systems that utilise colour as a vital componant in their design? I know that the london tube trains have colour coded seats depending on what line your on.

A lot of clothes stores utilize different colours for their sizing system. Most supermarkets define certain ranges with colours etc.

Brands have different colours too

Take the biggest brand of them all Coke, red for normal Coke, silver/white for diet, black for coke zero (replacing gold for caffeine free)
