Back in the day when I was using Firefox on my Linux machine I was able to make adjustments in Firefox that controlled print and background color and even made the banner disappear back then. I kind of liked that!
I have tried it here and so far the only background I have been able to change was individual newsletters where I have changed the background to a light cyan, a background color I have used in the past. I also like black print on a slightly darker gray background. For me, unless it is something natural like landscapes or flower photos I like to avoid a lot of flashy colors.
