The Redditor says the screen’s colors are “much better than the Colorsoft” and the prototype lets you adjust the intensity and saturation of individual colors. The size of the device’s screen bezels are similar to Amazon’s entry-level black-and-white Kindle, but they claim it will actually be a little smaller than the 11th-generation version of the e-reader.

According to the post’s author, the prototype’s user interface takes better advantage of its color E Ink screen, letting you change the colors of the battery, Wi-Fi, and shopping cart icons, as well as the reading progress status bar. The text of an ebook can also be colored and will dynamically transition from one color to another through four different shades as you progress through a book, giving you another visual clue as to when you’re near the end.
