So, can you please tell me what colour first comes to mind (taking into account criteria above), when you see these country groupings? Having each group a different colour would be preferred.
And also - what are my reasons for grouping the countries like this? Curious if anyone knows offhand.
Onto the groups... remember, groups, not each country individually.
1. France, Belgium, Luxembourg, Germany, Italy, Netherlands
2. United Kingdom, Denmark, Ireland
4. Spain, Portugal
5. Sweden, Austria, Finland
6. Latvia, Estonia, Lithuania, Slovakia, Slovenia, Czech Republic, Hungary, Poland, Malta, Cyprus
