Color

A new light-activated ink can change color on demand. It’s made up of colored microbeads that rise in response to different wavelengths of light to change a surface color, which could be useful for new displays or active camouflage systems.

Recent advances in ePaper technology have allowed for displays to move beyond e-readers and into tablet territory. Onyx International already has a monochrome 13.3-inch slate in its range, and has now added a 10.3-inch color E Ink tablet.

The challenge of creating next-gen OLEDs has been finding a way to improve color brilliance without lowering electrical efficiency. Now, researchers have found a way to achieve this by applying a fundamental scientific principle.

Back in April, E Ink announced a new color ePaper technology with improved update times, high resolution and stylus support. Now Gallery 3 is going into mass production and the first device to launch is the Bigme Galy tablet.

Last month, E Ink launched a new version of its color ePaper for digital signage called Gallery Plus. Now the company is back with a version destined for e-readers that boasts fast update times, high resolution and pen input support.

Around a year ago, we got to gawp at the latest color electronic paper display technology from E Ink when we reviewed the excellent PocketBook InkPad Color e-reader. Now E Ink has launched a new generation that gives the color performance a boost.

Back in 2014, we saw some of the first examples of color E Ink display technology. The first full color gamut support came a couple of years later, and now the color gamut and contrast has been bumped up again for E Ink Gallery Plus.

If mosquitoes seem to love you but ignore the person sitting next to you, the color of your clothes might be to blame. New experiments reveal that certain colors attract hungry mosquitoes, which could be used to design new traps or repellents.

Our mental images of the extinct thylacine, or Tasmanian tiger, are tinged in greyscale, since that’s the main way we’re used to seeing them. But now, one of the most famous videos of the animal, shot in 1933, has been professionally colorized in 4K.

China's Reinkstone has launched a 10.1-inch color e-paper tablet that runs on Android 11, which offers the kind of reading and doodling experience of the excellent Remarkable 2, but with the added draw of color.

Engineers at Stanford have created a new optical device that can easily manipulate light into basically any color desired. The system uses a series of modulators to fine-tune the frequencies of individual photons to change their color.

It may seem like a basic color, but blue is actually rather rare in the natural world. That complicates the search for natural blue food colorings, but now a team of scientists has found a promising candidate hiding in red cabbage.
