Associate to a ref column multiple fields

[Espegg]

I have in my table a two ref dropdown field (Dropdown 1) (Dropdown 2) that takes the sellers tables.
Now, I have other 2 tables:
Colors, Food.

I would associate for both (Dropdown 1) (Dropdown 2) two sellers and for each one (the sellers) Colors or Foods.

So, the question is, could I call with a Ref column or Enum/Enumlist column, two different tables?
