a oscuras/obscuras = in the dark
I don't know the reason but many of these expressions using adjectives become nouns are plural and feminine:
a ciegas = blindly (literally)
a oscuras
but other expression use nouns in plural (or singular) of any gender
a tientas = blindly (it literally means "by using the sense of touch")
a gatas = crawling (on your hands and knees)
a pedazos = in pieces
a gusto = comfortably
