In the 7 ball 7 group problem, every time a 7 ball group is forming, they need not be of different colour. For example if 85 balls are picked with 77 balls of same colour and remaining 8 balls which does not even form a same colour 7 ball group then we can see the requirement is not fulfilled.

If the points were allowed to be on the square, it would've been different I guess.
If 4 points were on the vertices and the 5th one was on the centre, minimum distance would've been root 2 over 2.
