Black or coloured papers, and non-black ink, cost more than plain white-ish paper and black ink.
Books don’t emit light in the visible spectrum so it does not make it easier on the eyes in low light conditions.
Historically it’s also cheaper because paper is some shade of white and it’s cheaper to not soak the page in ink.
Same reason that it’s uncommon for any page to have most of the page covered in ink, regardless of whether it’s a book or a sheaf of papers or whatever. Ink costs something, and it’s cheaper to put ink on a little bit of the page than it is to put ink on everything but a little bit of the page. Unless there’s a compelling reason to do otherwise, you take the cheaper route.
What if you use white ink on black paper?
You need to dye the paper. And the white ink would need to be suuuper opaque to even have a chance to be readable
Which is basically impossible to do
The Guardians of Childhood series has a few chapters that are printed in “dark mode.”
It’s way more expensive.
Hm. You can’t print it like that, it’d a ton of ink and too heavy.
Black paper and white ink? That’s interesting
Batman The Animated Series was drawn this way.
I’m a dark-mode person on computers, and I’m also a visual artist. When I draw digitally I always prefer drawing light colors onto a dark background, and when I paint I always prefer painting lighter colors onto a black-primed canvas. I think I first tried that after seeing a behind-the-scenes about Batman’s artists doing it that way, and realizing it made much more sense to my visual and artistic sensibility.
Ohh, that explains the really rich, deep colors they always used in the backgrounds. I loved the moody atmosphere that show managed to capture. Way ahead of its time, especially for a kids’ cartoon.
There are dark mode books? Just not that many.
@GolfNovemberUniform Its bad for your eyes to read in the dark, some kids books do have black pages and white text, like horror ones
