Color-Picking Pen Concept Imagines Real-World Photoshop Eyedropper Tool

Designer dreams up pen that perfectly replicates colors in the environment

Most of the Photoshop tools familiar to artists import old school analog devices onto the computer. Before computers, artists would use actual razors to crop, and physical scissors and glue to cut and paste. But South Korean designer Jinsun Park has envisioned a pen that reverses the process, taking a tool developed for the computer and porting it to physical reality.

Cooking green vegetables: why sous vide is better

Two of the main challenges when cooking green vegetables are retaining the verdant hues and emphasizing the fresh flavors on the palate. The battle against browning is often fought by blanching, which has the unfortunate effect of leaching much of the vegetable's flavor into the cooking water. We were looking for a better way.

New sets adjust the color themselves whenever the light changes

Tuner TV:  LG
To give you a perfect picture no matter how your room is lit, new TVs automatically tweak their on-screen colors to complement say, the orange glow of incandescent lights in the evening or the bluish tint of midday sunshine.

Color and Language

A new set of studies underscores the link between words and perception

If I told you my house were the only blue one on the block, you'd know how to find it. Whether it were powder or navy blue, our shared understanding of "blue" means we can communicate about color. Paul Kay, a researcher at the University of California, Berkeley, wants to know exactly what that means to our brains. Are we thinking about the color blue or the word we use to represent it?

The 11-Year Quest to Create Disappearing Colored Bubbles

Chemical burns, ruined clothes, 11 years, half a million dollars-it's not easy to improve the world's most popular toy. Yet the success of one inventor's quest to dye a simple soap bubble may change the way the world uses color

Tim Kehoe has stained the whites of his eyes deep blue. He's also stained his face, his car, several bathtubs and a few dozen children. He's had to evacuate his family because he filled the house with noxious fumes. He's ruined every kitchen he's ever had. Kehoe, a 35-year-old toy inventor from St. Paul, Minnesota, has done all this in an effort to make real an idea he had more than 10 years ago, one he's been told repeatedly cannot be realized: a colored bubble.
