Going Green with Color Technology: Variation in Plastics Makes Sorting Recyclables Easy

While various colors are visually appealing, there is a more important function to different hues: color-coding plays an important role in plastic recycling.

Color variation among plastic products may provide aesthetic appeal, but it is also is an important part of a color-coding system intended for a more eco-friendly world. Optical sorting has been an effective method of recycling and sorting in the glass industry for quite some time, and with an increased need for recycled plastic products, color sorting has now become the norm in the plastic industry as well.

Colorimetric Scores: Making Sure Your Tomatoes Make the Grade

The bright red color of the tomato can tell us a lot about quality and nutrition.

Color terminology has been changing; what we once called red is now referred to as magenta. Well, you know how the song goes: “you say tomato; I saw tomahto.” However, when it comes to color there is only one standard by which to abide.

Colorimetric scores are an important component for quantifying color in order to create the measurements needed to relate product quality to a grading scale. These scores have been developed through extensive research and analysis of tomato products at various stages of production to ensure color consistency and maturity. Various colorimetric methods and spectrophotometers have been used to revolutionize the tomato industry and lead to higher standards in all tomato-based products. Continue reading

Numerous studies have recently been conducted regarding color psychology. Color can tell us a lot about who we are, how we are feeling, and the choices we make. Why do people prefer their lemonade pink? And why is that “little pill” blue? Well, it is certainly not by accident. As human beings, there is a direct correlation between our senses and color. Color psychology not only impacts our internal thought processes, it also has a great deal of influence on consumerism — especially when it comes to pharmaceuticals. All major drug corporations know that color is one of the most important ingredients in prescription medications. That is why they depend on the highest levels of color technology and spectrophotometry in order to maintain consistency and accuracy in their product. Continue reading

Color Variations in Plastics: You Say Lime, I Say Chartreuse — What Is It Really?

The human eye is a remarkable tool in identifying color variations. In fact, the human eye can actually distinguish over 7,000,000 different color variations in our known spectrum of colors. Science and technology have explored the eye-to-brain connection of how light is absorbed and reflected, and these results have shown that the human eye is capable of distinguishing even the slightest deviations in color.

Despite how amazingly accurate and complex human vision can be, the eye and the brain do have their limitations. Optical inputs of color variations are altered by a variety of causes that lead to problems with visual analysis, especially in plastic manufacturing. Manufactures have to be incredibly precise when creating their products, to account for the variations in the way we see things, and to mitigate against their negative effects. Spectrophotometry tools are incredibly useful in this process.
