Depends what you mean.

Separate, with different values.

Returns the base (i.e., static) value of a given presentation
attribute as an object of type CSSValue

That will return a CSSValue with white (there is no canonical form
yet, though clearly rgb (100%, 100%, 100%) can express any of the other

getPropertyValue will, in the case of an implementation that
understands CSS, return a CSSValue most likely with the value black
unless there is a higher-specificity selector in a rule that sets it
to a different value. Which is possible, in CSS2, for example using
two id selectors, or an id and a class.
