Visual Evaluation: When the human eye is not enough for accurate color measurement

When driving today, the color of the landscape reminds me why I like this time of year. At my place, the trees started to change into bright tones of gold and red-orange. Every day we are amazed at the stunning visual assessment that our human eyes can have. Autumn is also a time of year, and I reflect on the colors of the local stores' lined islands when I consider the next autumn inspired wardrobe or decor to buy or comfort crockpot meals. The visual assessment of color once again inspired my senses ... and my purchase choices.

Amazing people's eyes

The eyes are one of the most important and complex parts of the body. Consists of more than 2 million working parts, second only to complex brains. There is no doubt why the vision is an important part of who we are and what we know about the world. Our visual assessment guides us in the way we feel about the choices we make in clothing, the food we eat and the products we buy.

Every day we use our vision to make decisions and choices that, although visually different from one person to another, are more consistent than our taste or smell. With the ability to decode up to 500 grayscales and over 10 million different color combinations, scientists and manufacturers are hoping to learn more about how colors affect the crowd.

Disadvantages of visual perception

There is no doubt that the human eye is an amazing tool no matter what its subjective behavior and in many industries it is still used to assess color standards. Visual assessment is a valuable tool in the manufacturing process; however, it does have its downsides. Although the eye has the ability to distinguish between so many different color patterns, it still lacks color memory and recalls the exact hue of the object it has previously seen. This alone may be problematic, but it does not even take into account that 8% of people with physiological dysfunction that cause their color vision will differ greatly from most people. Consistency in visual assessment can therefore become a nightmare of color assessment in manufacturing and manufacturing.

When the eye is tired, even the highest quality and well-trained eyes do not guarantee reliability. Individuals who must use their own optical functions on a daily basis often become victims of visual fatigue and chronic fatigue syndrome (CFS) many times. Symptoms of this type of fatigue include blurred vision, light intolerance, headache. This not only affects the individual's ability to visualize but also has a long-term impact and has been shown to cause permanent damage.
