Colors

Startup Duovox has launched a compact night vision camera with a custom Sony sensor and advanced algorithms at its heart that effectively turn night into day, bringing the full color experience to after-dark hikes in the mountains.

It can get tiresome, continually having to tell groups of children – or even adults – to be quiet. That's where a new sound-sensitive lamp comes in, as it does the job for you by changing color in response to rising noise levels.

Digital data storage is far from permanent. The data on your hard drive or flash drive probably won't last more than a few decades, but Harvard researchers have created what they say is a much longer-term alternative using spots of glowing dye.

Although some people may think that electric cars can run forever, their motors do wear out over time. According to a new study, special dyes could allow drivers and mechanics to know when that time is about to come.

Imagine if you were a product designer who wanted to see what an actual physical object would look like in different colors or patterns. Well, MIT has designed a system that allows users to easily do just that, utilizing photochromic dyes.

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.

Chronic skin wounds such as pressure ulcers can become very serious if left untreated, potentially even leading to amputations. A new "smart" bandage could help, by changing color before such wounds occur in the first place.

When a rope is heated – either by friction or by fire – it may lose its structural integrity, subsequently breaking when put under load. A new surface coating, however, could cause ropes to change color if they've been overheated, providing a warning to users.

It can sometimes be challenging for ophthalmologists, making definitive on-the-spot diagnoses of eye problems. A new "smart" contact lens is designed to help, however, by changing color in response to two common disorders.

A group of Polish entrepreneurs claim to have developed a pen that writes in almost any color, in the form of the Artera.

MIT scientists have developed a new system that allows coated objects to take on intricate multi-colored patterns when exposed to ultraviolet light.

​Even though road signs already tend to be highly reflective, some night-time drivers still don't notice the things. New technology could help, as it causes signs to reflect in an attention-getting rainbow of changing colors.
