10/20/2015 White Paper: Best Practices For Performing Visual Color Evaluation
Attempting a visual color evaluation is to determine the degree of difference between a sample’s color and the standard color. The method for establishing the procedure is usually straight-forward and simple depending on the industry or the company’s requirements. Today, many leading companies invest time and money to ensure the color of their products matched all the time.
Color can be measured instrumentally or viewed under controlled lightings to provide an objective color evaluation. Chroma Meters and spectrophotometers are used to measure color and light booths or cabinets are often used as visual grader. A light booth is a lighting cabinet with standard light sources such as D65 (Daylight 6500K), F2 (Cool White Fluorescent), Illuminant A (Tungsten) or industry specified light source. These light sources are useful in the evaluation of color and metamerism.
