Dark mode is a big appeal of any e-reader, whether it's a Kindle or another brand. And just about all models have it now that most e-readers include a front light. (Older Kindles don't always have one, so if you're getting an older refurbished one, double-check it.) However, one new model doesn't have a true dark mode: the Colorsoft. The Colorsoft can't have a full dark mode due to its screen design, according to Amazon, but instead you can switch the page color to black in the Quick Actions menu. It's not the same, though, especially if you are reading something that isn't a regular book (like a file sent to your Kindle) or want the menu pages to also be dark, you're out of luck.
