Rakuten Kobo is launching its first color e-readers, the Kobo Libra Colour<\/a> and the Kobo Clara Colour<\/a>. Both use E Ink’s latest Kaledio color screen technology, which has subtle, pastel-like hues and drops from a 300ppi grayscale resolution to 150ppi when you view content in color.<\/p>\n

The seven-inch Kobo Libra 2 is my favorite e-reader<\/a> outside of Amazon’s ecosystem, offering the Kindle Paperwhite’s<\/a> IPX8 waterproof design but with extras like physical page-turning buttons, no lockscreen ads, and more storage.<\/p>\n

The $219.99 Kobo Libra Colour retains all of those features but is also now compatible with the Kobo Stylus 2<\/a>, just like the Kobo Elipsa 2E<\/a>.<\/p>\n<\/blockquote>\n\n

E Ink’s color “Kaleido” screen technology has been around for several years<\/a>, but it’s gone through three generations now and devices that use the latest Kaleido 3 screens just started coming out last year.<\/p>

Color E Ink supports 4096 colors, which might sound like a lot but it’s actually far lower than a typical LCD screen. Colors tend to look softer and more subdued with E Ink, and color accuracy isn’t great, especially with certain colors, and it has more of a printed newspaper look.<\/p>

[…]<\/p>

The main drawback with color E Ink screens is they look darker than regular B&W screens because of a color filter layer that is applied over the top of the screen, which makes the contrast appear lower. Kaleido color screens are really just regular black and white E Ink Carta screens<\/a> with a fancy passive filter over the top (that’s why color resolution is lower than black and white resolution).<\/p>

Afterimage effects are more noticeable on color E Ink screens, where you can see a faint impression of the previous page. Color content may require more full page refreshes and flashes to look clear.<\/p><\/blockquote>\n\n
