I wish to have a black background for my browser screen especially in Chrome without any bugs.
Earlier, I had found a extension 'Color Change for Google' which worked only for the Google search page. Then, I found the following answer on this Google product forum:
Visit this site
then drag 'invert lightness' to the bookmark bar for easy access. This is a quick and easy way to flip most pages, framed or unframed, without too much hassle. The result is usually more legible.
I tried it myself and it works well within your conditions (Of course it would work only on white web pages, but most are white after all). Hope it helps!
