I can see things in it now! Just barely, but so much of an improvement for me

As Snarky said, a CRT is the oldschool type screen monitor, opposite of a flatscreen, and usually gives much richer colours. However, LCDs tend to brighten everything up, because unlike CRTs, they have to "show" colour, even if it is pure black, while CRTs would just show the colour at a less intense level, to make it darker. As a result, since everyone has flatscreens now, developers generally develop things for those screens, and me with my CRT is left behind.
Personally, I'm not a big fan of using literal darkness to show darkness of a scene in game, unless your actual intention is to not have the player be able to see anything as part of the gameplay (eg. those scenes in Fate of Atlantis where you had to set up a light in the underground dig). Even in movies, you'll notice that even when the characters are in darkness, you can still see them.
So like you have it now, a mostly monochromatic (but not monotonic) range of blue, just not so dark. Like in the first two Monkey Island's night scenes, Another World's night scenes, or Future Wars dark cave scenes, etc.
