Categorizing Colors by Criteria

This chapter discusses the importance of standardized color categorization systems for improving communication, especially regarding shades without precise names. European systems organize pure and mixed colors to enhance clarity, including purity levels, ranked orders, and attributes. Ancient Greeks and Romans used numbers and shapes in their classifications. The color wheel is a valuable tool that arranges colors in a circle, explaining phenomena like complementary color afterimages. However, different cultures have unique criteria for sorting colors. Some systems proceed clockwise from red, like Munsell, while others start counterclockwise from yellow, as in Ostwald. This chapter provides insights into Munsell Color Charts, initially developed for art education but later widely adopted for practical uses in agriculture, food production, and quality control. They played a key role in assessing soil color, identifying ripe fruit, and detecting defects in frozen French fries, agricultural products, and packaging.
