The design for the theme communicates the connection to your region, and is set by the system. Your community site communicates your community, but it also communicates the connection to the larger entrepreneurial movement in the region.
Techstars has an office in the following locations:
Techstars Europe - London
Techstars Latam - Mexico City
Techstars America - Seattle
Techstars Brasil - São Paulo
Your site picks up the regional color if it is in one of these regions. Otherwise, it will use the Techstars “green” color.
