Color Measurement 201

Which Color is the Hardest to Control?

Spectrophotometers are instruments that measure color. Manufacturers use them in every industry where accurate color is important, from paint and plastics to textiles, packaging, and even food. The data captured by spectros allow designers, brand owners, manufacturers, and quality control professionals to precisely communicate color and ensure it stays accurate throughout production.

Sometimes I’m asked which color is the hardest to measure and control. Can you guess what it is?

Even graffiti removal needs a little color measurement

Walking through the streets of Los Angeles, it’s no secret that graffiti is a huge problem. According to LA Weekly, graffiti-removal requests have increased by 64 percent in the last five years. City Administrative Officer Miguel Santana says that by June the Board of Public Works had already recorded 141,000 requests for the 2015-16 fiscal year, compared to 86,000 in 2010-11.

The Secret Life of Colorful Food

There’s been a lot of research around the role color plays in how we expect food to taste. The fact is, we judge flavor by the color of the food or drink, even before the first taste. We expect red foods to taste sweet like strawberries or cherries. White should taste like vanilla, and green is probably limey and tart or minty. Color cues can even determine whether we take that first bite. On the wrong food, like mashed potatoes or pumpkin pie, most of us won’t try green at all!

Green Pumpkin Pie

In the heat of summer – when a sweet, refreshing treat is all that’s on your mind – would you buy a brand of ice cream if the cartons on the shelf are off-color? The Algida ice cream factory in Corlu, northwestern Turkey, knows the likely answer is no. That’s why they came to us for help tightening their process control, so that each batch not only tastes great, but has uniform color.

As you can imagine, the color of ice cream – or any food for that matter – is not the easiest thing to measure. Here are the top four things manufacturers must consider when measuring food, and how X-Rite solutions can help.

Interesting Things our Customers Measure with Spectros

Whether it’s using Munsell Color Standards or one of our many color measurement devices, X-Rite helps manufacturers around the world achieve accurate color. We talked to our support team to learn about some of the most interesting ways people have used our equipment to measure and control color. From archeologists to fur traders and gastroenterologists, here are a few of our favorites.

In 2014, the city of Los Angeles used one of our handheld spectrophotometers to help remove more than 37 million square feet of graffiti. Instead of chipping a paint sample to take to the paint supplier or warehouse, contractors measured the color of the background and used the color data to mix the perfect color to repaint the surface.

Color management… for prosthetics? You bet.

For many of us, fun in the sun can lead to a summertime tan. The science behind this sun + skin interaction is melanin, a skin pigment our body releases to block the UV rays found in sunlight. The more time we spend in the sun, the more melanin is released, and the darker (or more freckled) our skin becomes.

This shift in skin tone doesn’t matter for most people, but for prosthetic wearers even a slight change can be a big deal. Here’s how Royal Preston hospital in the United Kingdom is using color management to ensure their patients’ prosthetics match, regardless of the color of their skin.

Can you see this man’s facial prosthesis? The color is so perfectly matched that it looks completely natural.

Are You Using the Right Tolerancing Method?

When visually evaluating color, everyone accepts or rejects color matches based on their color perception skills. In manufacturing, this subjectivity can lead to confusion and frustration between customers, suppliers, vendors, production, and management.

Are these acceptable color differences?

Are these acceptable color differences?

This is why color measurement devices are important in so many industries. By measuring colors using a spectrophotometer, you can communicate and compare spectral data for exact results.

To aid in color decisions, color acceptability limits called tolerances can be set as guidelines for how much perceived color difference is acceptable. Tolerances are used to control color, ensure consistency within a production run, and to minimize lot-to-lot variability. But even when using spectral data and tolerances to quantify color, customers and suppliers still find themselves disagreeing.

Why does this happen?

Through the years, different numerical ordering systems have been developed. If customer and supplier are using different ones, the tolerance – and acceptable color – will be different. Today we’ll look at the most common tolerancing methods so you can be prepared, no matter which method you are expected to use.
