The short answer is because the background color of the item you have
selected is in fact transparent.
Your style makes the <li> tag red. Then you query on a child element that
has no color specified. The background color of the child element is
'transparent' which means that the color of something up the tree is what
you will see.
You will never see 'red' by looking at the child element. But what you can
do (and jquery.color.js does this) is while you get 'transparent' then you
can look at the parent object. You can walk up the tree until you get what
you are looking for.
But before you go down that road, why are you looking to see the color of
the element? If you can describe what you are trying to do in more general
terms, someone may be able to give a better suggestion on how to accomplish
it.
