This website of Civitas Naturalis is about the rendezvous of forest and city. One of the two basic colours therefor is Pantone® Forest Green 17-0230 TPG. It is used in links, sidebars and menus.
The colour also symbolises in a broader sense nature in the Ecosystem City canvas. It is within that the functional component representing the natural environment as organism, surrounding the city and its life in it, but also being a high and essential value on itself.
