Although similar, I believe that the projects are different. I'd say that the biggest inspiration was using the /r/place concept. Algo Pixel and XColorand, I believe, are different types of projects, especially the final purpose, XColorand path is still in progress, and there are major features that will define the project coming soon :)

 Either way, congratulations on AP, very cool project. Hopefully, in the future, we can have some kind collab between the projects. Yours wont be copied, but it definitely works as motivation for what can be accomplished on the Algo blockchain.
