Different Visual Identity for different Package's Documentation

There is a lot of different very similar looking Documentation page, such as:

* https:// compas-dev.github.io/main
* https://blockresearchgroup.github.io/compas_rbe/index.html
* https://blockresearchgroup.github.io/compas_assembly/intro.html
* https://gramaziokohler.github.io/compas_fab/latest/

It is always a confusion to me that which Documentation I’m in and how to get to the correct one.
It maybe less confusing if they can have better/more different visual identity.
