I don't think OOo can render text with a specific outline color.
You can do it in Draw, but you'll have to convert the text to a curve, then you can set different properties for the outline and the fill however you like, but the object will be a pure graphic--the text is lost. If you needed to edit the text content, you'd have to start all over.
I think this is the relevant issue: Issue 42020
: Option to Make characters transparent in Outline Effect
