Support for "dark on light" terminal emulators

[v0lkan]

Yes "Mac guy"; yes I am on the light side, I use an IDE with light background, and all my terminals are configured to match my IDE background color choice. — And when you have a decent monitor, and a "decent" astigmatism mixed with some myopia, your eyes will thank you when you use a dark on light color scheme. — Though I'm not here to start a flame war :)

Thanks for the awesome work!

One issue for me is, I cannot use it with my current setup.

The current color scheme does not play well with a light terminal background.

An inverted alternative color scheme would really be nice.

If we could provide it via command-line options, it would be even nicer.
