Color fields in pivot based on group totals

[KongGulerod]

I have a dataset that I view in a pivot table. To make it easier to view I want to color the table based on the total of the group. If the group total is blank I want it to have a color. But I also want the rest of the fields in the group to be colored. Is it even possible? The data is dynamic and is changed on a weekly basis. The original data is not about what people drink...

Data example:

Department	User	Drink
Dep1	Usr1	Beer
Dep2	Usr2	Beer
Dep3	Usr3	Wine
Dep1	Usr4	Water
Dep2	Usr5	Beer
Dep3	Usr6	Beer
Dep1	Usr7	Water
Dep2	Usr8	Water
Dep3	Usr9	Beer
Dep1	Usr10	Beer
Dep2	Usr11	Wine
Dep3	Usr12	Wine
Dep1	Usr13	Beer
Dep2	Usr14	Beer
Dep3	Usr15	Wine
Dep1	Usr16	Water
Dep2	Usr17	Beer
Dep3	Usr18	Beer

The Pivot looks like:

My conditional rules looks like:

What I really want my Pivot to look like (colored by hand):

I can not seam to find a solution.
I fear it's not possible.
