Thread:Semantic-mediawiki.org:Community portal/Extremely basic question about properties with multiple values

I feel like I'm missing something obvious here, but I do not understand how to select pages with #ask where a property with multiple values shouldn't have a certain value.

I'll just use the demo pages here for an example: It seems to me like this query should select nothing, but it it renders, due to that page's "Located in" property having multiple values, both Europe and United Kingdom. (According to the definition of the ! operator, this is technically the expected behavior, i.e. England is a page that does have a value other than Europe for it's "Located in" property.)

So the use case I have is a property where the values do not even have a hierarchical relationship. For example, let's assume we have pages with a "Has colors" property that can have more than one value of red, green, blue, etc. How would I go about selecting pages that are not red ?
