Border

I asked a group of people if they liked the adverts with or without the border, and everyone said they preferred it with a border.

I then showed them eight different types of borders, where the colour of the border corresponded with the colours of the bottom block, and asked them to vote on which they preferred the most.

1. 2 votes
2. 2 vote
3. 0 votes
4. 1 vote
5. 3 votes
6. 3 votes
7. 0 votes
8. 0 votes

As you can see, the votes are quite close between 1, 2, 5 and 6, which means the final decision is up to my personal preference.
