Unfortunately a dark colour in early photographs tells us very little, except that it is probably not blue!
This illustration was used by Kodak in 1931 to introduce their new Panchromatic film and to show how colours were rendered on the new and old film stock:
Basically, anything rendered a dark colour could be black or dark grey, green, red, even yellow! On early film only colours in the violet to blue spectrum would react to give a lighter shade, so that lighter shade could be navy blue!

As Mike says this is all about the difference between orthocromatic and panchromatic films.
The earlier orthocromatic films are more sensitive to blue and green. Hence 'old' pictures taken without filters where the sky looks dark and the clouds are accentuated. As has already been said green would also be seen as dark.
Panchromatic films started to show up in the late '20s as I understand it.
