How to change Maschine MK3 group/page button colors in de controller editor?

Mavros

I have created several pages in the controller editor to run Maschine in midi mode. All works but the group buttons, in midi mode page buttons, are all the same color. In the controller editor manual it says this color is linked to the page however I cannot find how to change the page color.

I edited the .group colors in ncc file manually with an xml editor but that does not work.
