Multiple Location differentiator

No can do at the mo.

If you are after a single linear list of taxonomy terms, then as a workaround: combine the taxonomy terms from two vocabularies in a new vocabulary and use that in the Location differentiator.

If your question is in fact about having to location differentiators that together produce a cartesian product of combinations, each of which should have a colour, or colour-pair assigned, then no you cannot do that.

Considering this fixed, unless re-opened.

I have found a workaround after a lot of research. Maybe it is interesting for someone.
I have 2 category fields that should show specific marker for each combonation.
So I added a simple text field in the Content type. Via Field Permission you can set it to hidden. I don't want to see this field.
Now I added simply a rule to fill this field after creating or editing a content with the values of both category fields. Result is "Cat1value-Cat2-value"
Now I use the hidden fiel for choosing the differentiator and it works well.

Very clever Likos73.
