The Kindle Colorsoft carries a US280 price tag that compares with similar devices from other manufacturers available on Amazon in the range of 149 to 330. The Colorsoft relies on LEDs and other technologies to achieve the colour display, according to a company statement.
Amazon had tried in prior years to develop colour e-readers using eInk the technology available in its standard Kindles that requires minimal battery power. The Colorsoft will have a roughly eight-week battery life, compared with up to three months for its latest generation Paperwhite e-reader.
The Seattle retailer also unveiled a new Paperwhite with a 7-inch screen, measured diagonally, two-tenths of an inch larger than the most recent generations. It also revealed an updated Kindle Scribe e-reader, which allows users to jot onto the screen with a stylus and convert that into more legible text.
Users in-book notations can be summarised by artificial intelligence software that can convert pages of notes into bullet points, the company said.
