Amazon just launched four new Kindles, including a full-color model. Here's what's new

Amazon just announced a new Kindle lineup, including the Kindle Colorsoft, the company's first full-color e-reader. The announcement also includes a new Kindle Scribe, Kindle Paperwhite, and a standard Kindle.

The Kindle Colorsoft is the most intriguing model of the bunch, being a waterproof, full-color, 7-inch e-reading tablet with up to eight weeks of battery life. It's Amazon's first time delving into a color e-paper display, which competitors, like TCL, with its Nxtpaper display, have mastered. But unlike Nxtpaper, the Kindle Colorsoft doesn't switch from full color to black and white, giving Kindle users a more vibrant alternative to view book covers and color highlighters at all times.

Amazon says the new Kindle Colorsoft "uses an oxide backplane with custom waveforms for fast performance and a higher contrast on both color and black-and-white content." The glare-free display has a new light guide with nitride LEDs to enhance color and brightness settings. In addition, users can choose from a standard or vibrant display style. 

The Kindle Colorsoft maintains the e-reader's core purpose: it doesn't have notifications or social media, giving readers an uninterrupted, yet colorful, escape. It also supports wireless charging, has fast page turns, up to 32GB of storage, and has an auto-adjusting front light to read in dark and bright settings. 

Customers can purchase a new Kindle Colorsoft for $280, with orders shipping on October 30.

Amazon also announced a new Kindle Scribe, featuring a redesigned, flush-front 300-ppi display with white bezels, built-in artificial intelligence (AI) features, and a Premium Pen. The Kindle Scribe now lets you access AI in notebook tools, automatically summarizing and refining notes into concise bullet points displayed in a script font to seamlessly blend in with handwritten notes. 

Kindle Scribe users can also take notes directly on books using Active Canvas. When they do, their notes will look like they're part of the page, remaining visible regardless of formatting changes. 

The new Kindle Scribe is available for preorder now, starting at $420. Orders will ship on October 30. It's available in two colors: Tungsten and Metallic Jade.

Amazon claims the new Kindle Paperwhite features the highest contrast ratio of any Kindle, thanks to an oxide film transistor used by the display. The 7-inch Kindle Paperwhite is waterproof, features 25% faster page turns, is more responsive, has 16GB of storage (or 32GB for the Signature Edition), and can last up to three months on a single charge.

You can preorder the new Kindle Paperwhite in Raspberry, Jade, and Black today for $160. Orders will ship on October 30. You can also preorder the Kindle Paperwhite signature edition at $200 in Metalic Raspberry, Metallic Jade, and Metallic Black.

Finally, Amazon also announced a new standard Kindle, which it claims is the lightest, most compact model yet. The 300ppii glare-free display offers faster navigation, 25% more brightness, and weeks of battery life.
