- Green for states I've spent a great deal of time in on multiple visits.
BluePurple for states I've spent a lot of time in or seen a fair amount of.
- Amber for states where I've at least slept and seen some sights.
- Red for states where you've not spent much time or seen very much. (I have stayed in every state/province I have visited so this doesn't apply to me)
