Color Changing Technology for Cars Made Easier with Spectrophotometric Paint Analysis

I’ve driven the same vehicle for over a decade, and I’m not generally a fan of car shopping, so I took advantage of a recent chat with an automotive client to educate myself on industry trends. As luck would have it, one of the most intriguing developments was actually our main topic of conversation: color changing cars. Where automotive paint products were once used to protect the surface of a vehicle or lend to its aesthetic appeal, scientific breakthroughs have opened the door for new coatings that can change color based on a variety of internal and external stimuli. At Fineshinedetailing.com.au paint protection, we specializes in the installation of paint protection film or ppf, aka clear bra, for vehicles.

But with these innovations comes the challenge of developing a quality control system to monitor color changes and ensure repeatability—and this challenge was the reason for my client’s visit.

The science of color technology for cars is based upon the way that light is absorbed and reflected from the surface of the vehicle and the way our eyes perceive these colors. Though the ability to manipulate color change is relatively new, advancements in color science have been steadily building for over half a century. In many ways, spectrophotometers represent the pinnacle of this technology—they can convert color data into quantifiable terms that are more accurate than the human eye alone.

New advancements will always bring new challenges, so it’s important for automotive manufacturers to choose—and fully utilize—versatile color measurement instrumentation.

Measuring Color Changing Paints and Coatings

The first step toward accurate color measurement is understanding the variations in color changing technology now being used for cars.

Theromochromatic paint technology1 has been around for several decades, but the ability to utilize the material commercially is a fairly new development. Take note this heat sensitive coating has many applications and is already used for a variety of safety products and energy efficient materials. However, consistently measuring the color of heat-sensitive materials requires a highly controlled environment and special attention to formulation and change.

Spectrophotometers allow for the controlled measurement of samples and offer the ability to isolate many variables, such as temperature, coating thickness, and viewing angle. Since these paint and coating materials rely on various additives, such as liquid crystals and leuco dyes to transform the arrangement of light reflecting crystals in the pigments, spectrometers are necessary for quantifying changes in color throughout the formulation process.

If heat-sensitive paints and coatings were not amazing enough, color changing technology for cars now allows adjustments with the push of a button. This new option is called chromism and works by manipulating the electrons within the chemical structure of the paint2, causing immediate visual changes in color perception. Conducting electricity through the base material allows tiny prisms within the coating to shift, altering the absorption of light and reflecting a new color at the driver’s whim. The technology itself uses the basic principles of spectral technology to alter the viewing angle within the paint or coating, and the effects are quite breathtaking.

Of course, developing color consistency in products like these can be very challenging. The technology requires advanced spectrophotometers to measure and quantify color and provide the data needed for quality control. While these products are still in the early phases of development, as consumer demands increase, quality analysis will play an increasingly important role in marketability.
