For example:

Red = Active
Green = Active - added in last 2 years (not colour coded for whether the site was "grey" last time, or not).
Grey = "Coming soon". NOT on the map 2 years ago.
Pink = Grey 2 years ago, still "coming soon" grey.
Blue = Grey last time, disappeared since. Some (such as Ipswich (grey last time), and Colchester (under construction) are "somewhere near each other" and presumably reasonable to consider as replacements for each other ... but definitely not if your plan had a requirement for it to be at Original Position).
