Well, this is how it looks like on my laptop:
I can't conveniently take a photo of that, because of obvious reasons, but this is as accurate as I could get.
Otherwise, take a look at this:
Hmm, maybe I tweaked my laptop's display settings
See, I normally increase the contrast, and then add a bit of brightness, when it comes to that. My monitor settings (and in-game) are definitely different than yours, so...
Edit: (11:49pm)
I've noticed 1 thing in particular. TWHL's colour scheme is very bright with little contrast.
Contradictory, my screenshots are somewhat dark. Try viewing the screenshots in full-screen mode, or just zoom in, so your eyes can adjust to the darkness.
I've actually experienced that IRL multiple times =P
I got this idea an hour ago when I got out of my room (and it's night a.t.m.) and it was very dark. I still saw everything.
I went to the bathroom, turned on the lights [...] and then came out, 30 minutes later. I couldn't see anything after switching off the lights!
I stood in the hall for 1 minute, and shortly, I saw the walls again, then the carpet on the floor and so on.
But meh, this probably won't work with this exact scenario =(
