How can i Differentiate pin cluster for multiple combination.

[balkrishanyadav]

This is very good cluster example. I am implementing in my own project but i have a issue for cluster type.
I want to show three type of circle for 2 different category(A & B).
I have 2 type pin which makes three combination of cluster circle.
-> One for pint type A
-> Second for pint type B
-> Third for pint type A & B Both
If Cirlcle have only pin A type then circle color for A_color.
If Cirlcle have only pin B type then circle color for B_color
If Cirlcle have only pin A & B Both type then circle color for combination of A & B color
please help me for this combination how can i achieve in my project.
Thanks
