Unlike cats, our vision is pretty rubbish in very low light conditions. Fortunately, technology can help us reveal the hidden secrets of the night. The Nightra is just such as gadget, and promises to reveal "every detail in vivid, full color."

Imagine having a picture on your wall that completely changes when the room gets too warm. Engineers at MIT have created a new printing technology called Thermochromorph to make full-color images that switch in response to temperature.

Color E Ink has been in the wild for a while now, and we've featured a number of reading and note-taking devices that use it. Amazon's popular Kindle range has so far stuck with shades of gray. That's changed with the launch of the Kindle Colorsoft.

Ordinarily, the 3D printing of multi-colored objects is a relatively complex and inefficient process. That could soon change, however, thanks to a clever new technique in which a temperature-sensitive print media gets "ironed" after being extruded.

Duovox has followed its successful Kickstarter for a military-grade night-vision monocular with a Pro version that promises to bring the hidden darkness into "true full color." The nocturnal adventure gadget is also joined by a teeny smartphone camera.

Speaking a language with different words for different color shades means the brain perceives those shades quicker than using a language with only one word for that color, highlighting the interaction between language and perception according to a new study.

The PocketBook Eo color E Ink e-note announced back in April is now available. We've spent the last few weeks being kinder to our eyes while makes notes, reading and planning – and have even taken the odd photo. Let's have a closer look.

An amphibian has lived up to its name, swapping out its usual green coloring for bright blue, in the first-ever record of a magnificent tree frog with this appearance. It's stunned scientists, who know they're unlikely to see this again.

The Disney-esque hues on bluespotted ribbontail rays come from a unique arrangement of nanostructures, say researchers. The findings, along with those gleaned from studying blue sharks, could help lead to new chemical-free color techniques.

Bigme has launched a color E Ink tablet that's billed as the first to run Android 13 out of the box. The latest InkNote has access to Google Play, sports a 10.3-inch Kaleido 3 color display with stylus support, and comes packing front and rear cameras.
