Radio station - Kaleido 3, Gallery setup 3, and InkNote Color application
In the rapidly evolving world of e-readers, two promising advancements in color E Ink technology - Kaleido 3 and Gallery 3 - have been making waves. These innovations offer improved color saturation, richness, and faster refresh rates, particularly for Gallery 3. However, the broad adoption of these technologies in large devices has been hampered by manufacturing delays and capacity bottlenecks.
Kaleido 3, the third generation of E Ink's color e-paper technology, features a color filter layer over the black and white layer, producing 4096 colors with a color resolution half that of its black & white layer (300 PPI black & white, 150 PPI color). Gallery 3, on the other hand, uses microcapsules with cyan, magenta, yellow, and white particles, enabling over 50,000 colors with better contrast and more vivid colors than Kaleido 3.
Despite their potential, these technologies have seen limited inclusion in commercially available products as of mid-2025. The main reason for this is the challenges faced in manufacturing large-screen versions of Kaleido 3 and Gallery 3 e-paper displays. E Ink had planned large-screen e-notebooks for 2025, but their new production line (H5) has faced technical bottlenecks, operating beyond capacity, and unable to meet demand or produce enough units on time.
This has led to delays in the launch of large-scale color e-readers, such as the Kindle Scribe Color or Elipsa Color, which were initially expected to hit the market in early/mid 2025. These devices may now be pushed back to Q4 2025 or later.
In contrast, mid-sized e-paper screens - smaller color and black & white displays - are more readily available. This is why more smaller e-readers with color screens are being launched by brands like Boox and Kobo, and Amazon recently released a Kaleido 3-based Kindle model (Kindle Colorsoft) in late 2024.
Our platform Radio, hosted by Michael Kozlowski and Peter, will delve deeper into these topics, discussing a co-branded color e-reader with Bigme and our platform.

Gadget enthusiasts might eagerly anticipate the arrival of larger color e-readers, such as the Kindle Scribe Color or Elipsa Color, due to their potential delays into Q4 2025 or later, caused by manufacturing challenges with Kaleido 3 and Gallery 3 e-paper technology. Meanwhile, mid-sized e-readers with color screens are increasingly becoming more common, with brands like Boox and Kobo releasing new devices, and Amazon launching a Kaleido 3-based Kindle model (Kindle Colorsoft) in late 2024.
