Enforce style of named list items in Excel 2010

Question

I have a named list with some values which have their own style (e.g. different colors):

How can I get the style of the named list values to be applied when re-used in a data validation list?

Answer 1

The most lightweight way to solve this problem is to set up 4 different conditional formatting rules for the cell with the dropdown. Each rule would be something very simple, like =B2="+" applied to B2.
