Coloring Athens has been designed as a sustainable, low-cost open data/knowledge exchange platform that can be replicated by other cities using its open source code.

It is developed by a small, dedicated team at The National Technical University of Athens. We are unable to answer individual queries but we welcome constructive comments on how to improve the site, and on other types of data and new features you might like to see.

You can send us comments or ask questions on our discussion threads at
