E Ink says it combines a color filter array with its Carta black-and-white ink film, supports 4,096 colors and 16 grayscale levels, and delivers 30% higher color saturation than the previous Kaleido Plus generation. Those figures are the company’s claims, not independent test results.
How Kaleido 3 produces color
E Ink describes Kaleido 3 as a pairing of a color filter array (CFA) and E Ink Carta black-and-white ink film. The filter array enables color content while the underlying display technology provides grayscale rendering. E Ink’s announcement identifies the technology for eReaders and eNote devices that display colorful images and information.

What E Ink reported for Kaleido 3
| Claim or detail | E Ink’s announcement |
|---|---|
| Color palette | 4,096 colors |
| Grayscale | 16 levels |
| Comparison with Kaleido Plus | 30% higher color saturation, as reported by E Ink; not an independent comparative measurement |
| Module sizes listed | 7.8-inch, 10.3-inch, and 13.3-inch modules |

The sizes refer to modules named in the 2022 announcement; they do not mean every size is used in a current retail product. The 30% figure compares reported color saturation with Kaleido Plus, not overall device quality or a complete panel-to-panel evaluation.

What Kaleido 3 means for a device buyer
Kaleido 3 is a display technology, not the name of a standalone reader. E Ink’s announcement establishes intended uses and panel details, but does not identify a current Amazon retail model or confirm which consumer devices are available now. If a product listing says it uses Kaleido 3, check the manufacturer’s specification for the exact model rather than relying on the display family name alone.
For readers comparing color e-paper devices, the announcement provides a useful generation-level claim—higher color saturation than Kaleido Plus—but not enough to rank finished products. A device’s actual suitability depends on its own documented specifications and use case; the panel announcement alone does not establish how a particular model performs.
