Hmm... well, I tried changing the background fade color, and it had no effect. Even when I put in crazy numbers like R:0, G:255, B:10. I noticed that it helped when I changed the water blocks for some reason. The colors were still off, but they changed from whitish to greyish. Then, I changed the water blocks again, and it changed to really bright white. It's weird, because the water blocks do not contain only shades of blue and grey, while the background contains only shades of green (with a very slight touch of blue).
