What should be excluded?

So, we have several levels in this game, you should choose figures on each of them, the figures should differ from all the rest.
What are the differences?
I don’t want to give you direct hints, that’s why you should try to look at the picture and answer the following questions:
– Do all figures have the same form?
– Do all figures have the same color?
– What are the differences between the figures?
– Are all figures colored?
These are not all questions but I hope you understand the idea:)

Catching butterflies!
