Chroma Club, monthly coloring book subscription

I just launched this little side project, it's not entirely on typical HN topics since it's coloring books, but I thought there might be some interest.

I'm exploring a few idea around augmented reality to enhance the coloring experience and be a proof of concept of augmented print content (I haven't seen much else on that field besides some advertising)

Would love to field any questions or garner some feedback. Thanks
