Let's discuss the category colours. While there should not be a hard-and-fast scheme for all categories - we would like to leave it up to communities to choose their own colours - we would like to have the project colours associated with the categories of the projects.
For Sci-GaIA, this means that the Sci-GaIA and Meta are reserving the following colours:
- foreground : #13643A
- background : #FBB900
Other projects such as TANDEM and Magic can decide on their own
