You may not think that a colour chart (or color chart, for our American friends) is either that important, or that useful for anything.
However when you’re buying Lego parts online, the name of a colour is quite important, especially when some Lego colours are so similar to each other.
This videos goes through which pieces I use for my colour chart, what I use it for, and also shows all the colours it currently has.
