Entrepreneurs in Denmark have taken another step towards improving the general usability of 3D printers with the Diamond Hotend, a single 3D extruder unit that can mix and melt three filaments together and produce items in a rainbow of colors. Read More
A thin and flexible chameleon-like material developed by engineers at the University of California, Berkeley changes color when stretched or bent even tiny amounts. With potential applications in camouflage, structural fatigue sensors, display technologies, and more, the material's color changes reliably as it gets flexed thanks to rows of ridges that are precisely etched onto a silicon film one thousand times thinner than a human hair.

Most people probably don't think of a coating of paint as being a particularly major component of a manufactured item. If the object is quite large, however, or if a lot of them are being made, paint can add considerably to its weight and/or production costs. With that in mind, researchers from Harvard University's Laboratory for Integrated Science and Engineering have created a new lightweight, low-cost coloring technology for both rough and smooth surfaces.

Researchers at Rice University's Laboratory for Nanophotonics (LANP) have developed a new image sensor that mimics the way we see color by integrating light amplifiers and color filters directly onto the pixels. The new design enables smaller, less complex, and more organic designs for CMOS (complementary metal-oxide semiconductor) sensors and other photodetectors used in cameras. Read More

Back in May we reported on plans to create the Scribble – a pen that can scan and reproduce any color you can find on the fly. After the project smashed its Kickstarter target in just five hours, those plans are now one big step closer to reality. Read More

In good news for parents who don't like watching their little ones become tablet-clutching screen zombies, games are increasingly merging real-world play with digital experiences. Chromville is an app which brings children's coloring to 3D life with augmented reality, and lets them use their creations in on-screen games. Read More
If you want to sample a color that you encounter in the real world and then reproduce it on your computer, you might already be interested in devices like the SwatchMate Cube or the NODE Chroma module. Sometimes, though, you might just want to do some freehand pen-and-ink drawing using such "captured colors." That's just what Scribble's upcoming Ink color picker pen is designed to let you do.

Finding the exact shade of lipstick or eye shadow you have in mind can be tough, which is why Grace Choi, a Harvard Business School alumni, came up with the Mink – a 3D printer that lets you print out makeup in any color you fancy. Whether it's the color of a fruit, your friend's purse or a sunset, transforming that color into any kind of makeup is simply a matter of choosing it and hitting print. Read More
A beautiful stained glass installation, a colorful billboard, or rows of windows on an office building ... all as electricity-generating solar cells? New research at the University of Michigan gives a method for creating such transparent and colorful solar cells using a hybrid silicon/organic composition, and furthermore avoids some of the problems of previous colored and transparent solar cells.

When the sun goes down on your high tech surveillance operation, outside location broadcast or wildlife documentary shoot, there's a good chance that your world will fade to shades of green and black. Tokyo's Komamura Corporation is readying a new handheld camcorder called the Falcon Eye KC-2000 for release, which brings a splash of color to scenes too dark to be visible to the human eye.
