I have slightly changed some of the colours used on the site to create more distinction.
The major change is to the colours used for eu countries.
Countries which were members of the EU when my travels started in 2001 remain in the original colour scheme
Countires which have joined the EU since 2001 (e.g. Czech Republic, Hungary, Latvia etc) have a slightly darker colour
A list of EU member states (and those applying for EU membership) with their joining dates can be found in the download section of the help pages
