Hack: Make PDFs Amber-on-Black

Fri, 23 Jan 2026 21:57:36 -0500

Recently, I wanted to read a scanned PDF on my Kobo. The white-on-black PDF was quite “bright” for my tastes as I usually read at night. The Kobo supports dark mode for epubs but it doesn’t seem to have a means of inverting the colour of PDFs natively. Moreover, I like to read things as amber-on-black. A bit of vibe-coding and fiddling around yielded the following terrible script to make a PDF “amber on black.”
