     Adult females can show quite a bit of blue in the flight feathers.

Hi,
     
I had read the discussion about young Black-throated Blue Warbler males 
looking basically like adults before migration and felt like I had 
observed exceptions to this.  I did not comment because I wasn't 
positive even though I had once taken a very poor photograph of one. 
Yesterday I saw another:  It had blue wings, rump, tail (I think), and a 
large white check mark at the base of the primaries.  This was very much 
like the adult, but the blue was not as blue.  The rest of the plumage 
was female-like:  The head, nape and back were brown and contrasted with 
the adjacent blue, the supercilium was white; there was a white crescent 
under the eye, a light area outlining the lower edge of the cheek and 
pale underparts with a yellow cast especially across the breast and 
along the sides.
     
Good Birding,
