The dotted circles are a metaphor for an ideal society, with porous and intersecting perimeters of groups of people.
Regardless of the reasons that make groups seem open or impenetrable at any given moment, groups are made of people who each want to live a full life. That’s why they join and create groups with others! So, despite overt and implied rules by which people are included or excluded from different groups, intersecting circles is a valid representation of society. You are never isolated. There are many groups to which you can belong.
Welcoming and serendipitous opportunities – the things that keep boundaries porous – help keep society open, functional, and optimistic.
Finally, if I wanted to be esoteric about it (and perhaps I did), the purple is in homage to Prince, purple is a colour of creativity, knowledge, and innovation, and the Easter colour scheme is in reference to perpetual change: dying and being reborn, our multifaceted, divine nature.
