Color-changing Properties Make Gold Multi-purposeful

Color-changing products have been mesmerizing consumers for years. When did you receive your first mood-ring or hologram trading card? While holograms reflect light to reveal different colors and images, mood-rings change hues based on a person’s body heat. Now, a new color-changing product is in the works but it does not rely on light or body heat in order to change. Instead, it changes based on touch.

Scientists at the University of California have found that when gold nanoparticles are strung together, the collective color is blue. Then, when these strands break apart, they continue to change colors into purple and red. The final color is determined on how much stress is put on the gold. If it is lightly touched, it will change to purple; when it is completely broken apart it turns red.

As of right now, there is much excitement about using these gold nanoparticles in paint, tape or bandages so that color-changing properties can be used to indicate how much stress has been applied to a particular area. The inventors envision this being used in products like vehicle crash-test dummies, performance sports equipment (such as baseball bats) and beds. When used in these capacities, the color-changing product may indicate where the greatest amount of impact is concentrated.

While a number of comments on The Atlantic Magazine article suggest the color-changing properties of gold is not a new phenomenon, the technology to make it marketable might be. Because the concentration of gold is low, this could become an affordable, household product. However, scientists are also looking at the less expensive alternative silver as a possible composite. Like gold, when silver is broken down it changes colors but because it lets more light in, the nanoparticles will change from blue to green to yellow.

This new discovery may be available to the public soon. Right now, a patent is pending for the University of California scientists. Before long, gold nanoparticles may be in our tape, paint and bandages – and for good reason too. It will be help us indicate where impact has been made by changing its color with a simple touch.

Vehicle Safety and Car Color

Vehicle Safety and Car ColorDid you know Volvo was the first car to incorporate seat belts? Advanced safety features come standard in many cars now. Some are even required by law. One way to make a car safer is to choose its exterior color wisely.

When looking to purchase a new vehicle, do you ask how safe its color is? This seems like a far out question but, as of late, studies are circulating about what happens when vehicle safety and car color collide. From a scientific standpoint, there is not enough research to back up these studies yet. Regardless, all research points to silver as the safest car color.

Car Color Safety Studies

  • Daimer Benz found that lighter car colors are more conspicuous than darker shades. This has to do with the way light colors draw attention from other drivers when on the road.
  • The University of California claims color influences how well individuals can judge distance between vehicles. Bright cars seem closer while dark colors appear further away. Light car colors are most accurate.
  • The University of Auckland in New Zealand made a connection between how the color of cars correlate with “rates of injury causing accidents.”

Silver is the Safest Car Color

Silver cars rank highest on the list of safe car colors, but light color cars are safer than darker vehicles. Lighter colors reflect more light than darker colors do. This means white and silver cars are easier to see from farther distances. They are more visible on the road.

The Role of Color Psychology

Did you know other vehicle colors on the road may impact how you react while driving?

Because colors can encourage a wide range of emotions and spur on energies that range between aggressive or calm, it makes sense that colors of surrounding cars may enhance our moods to some degree.

While no one is certain if car color is the newest safety feature, studies show darker color cars are involved in more accidents that lighter color cars. From this research, we can draw the conclusion that it is easier to notice light cars than darker ones.

How important is vehicle safety to you? Would you choose to drive a white or silver car based on this information?  What is your favorite car color and why?
