Like geographic coordinates – longitude, latitude, and altitude – L*a*b* color values give us a way to locate and communicate colors. What’s the history of L*a*b*? In the 1940’s, Richard Hunter introduced a tri-stimulus model, Lab, which is scaled to achieve near uniform spacing of perceived color differences. While Hunter’s Lab was adopted as the de facto model for plotting absolute color coordinates and differences between colors, it was never formally accepted as...
When it comes to the way we see color, our eyes can be deceived. This is partially caused by our humble brain, which is managing vast amount of information and processing it the best it can. It can also be related to genetics and the environment; we all see color a little differently. But above all, LIGHT has biggest impact on the colors we see. Without getting too technical, here is an introduction to the way light affects our perception of color. RGB Color Circle The temperature of lig...
If you’re measuring wet and dry paints, plastics, cosmetics, or small and odd-shaped samples, you’ll want to take a look at our new MetaVue VS3200 non-contact imaging spectrophotometer. It’s the perfect choice for industrial applications in coatings, plastics, food, cosmetics and more. Today we’ll demonstrate the power of its smart spot and on-screen targeting features and explain how it can integrate seamlessly with your formulation, quality control, and performance opt...
Warm weather is just around the corner and spring is in the air! Fluffy yellow chicks… Delicate pink tulips… Soft green sprouts poking through the ground… And, of course, spring M&M'S®! Advertisers target our springtime emotions through pastel colors. Pastels have a calming effect, and everywhere you look companies are using them to feed our desire to feel a bit of spring. Today we’ll take a look at the psychology of color, how marke...
When customers are just getting started with color management, they often ask, "What is the difference between a spectrometer and a spectrophotometer?". With such a minute spelling difference, it's easy to make a quick typo and get the wrong answer for this color question. So...what's the difference? Spectrometers vs. Spectrophotometers What is a Spectrophotometer? A spectrophotometer is a color measurement device that is used to capture and evaluate color on just about anything, in...
The two most common spectrophotometers are the 0:45 and the sphere (aka diffuse/8°). We get a lot of questions about which is the best choice. Here’s the difference in how these two devices measure color, and guidelines for when to use each. 0:45 In a “fixed geometry” or “single angle” device, the first number is the starting point of the light, and the second number is where the light ends up after the reflection off the surface of the sample. In a 0:45 ...
Using a light booth to visually judge color is a great start to a successful color evaluation program. It allows you predict how color will look under multiple light sources so there won’t be any color surprises when the light changes over the life of the product. Introducing a color measurement device to capture spectral data is the next logical step. For a really great color program, you need to use both a light booth AND a spectrophotometer. This dynamic duo offers benefits you can&rsqu...
If you work behind a paint counter, you know customers can surprise you with interesting and unique objects to color match. Many samples are relatively easy to measure, but when a customer shows up with a curved baseboard panel, a square of shag carpet, or a plush toy, things can get a little tricky. A few years ago, we learned just how challenging it was for our retail paint customers to color match unique samples. We took in a bag with textured and multi-colored items and asked the person behi...
Recently we blogged about how appearance affects color. In this article we look at some of the characteristics that impact an object’s appearance, such as texture, gloss, transparency, and special effects, and explain why it’s crucial to describe appearance in the early stages of the design workflow. While 3D programs have attempted to address appearance aspects for years, there has been a missing link in virtual product design: the ability to integrate characteristically &ldqu...
Whether purchasing a new car, consumer electronics, or household appliances, color consistency influences the perception of quality. If the color doesn’t match from front-to-back and side-to-side, customers will likely question the quality and move on. That’s where color measurement can help. In today’s competitive marketplace, manufacturers are going beyond color to utilize extreme effect finishes to differentiate their products. But, as manufacturers are quickly learning, me...
