students in this vocaltional education course had read about the "sea-son" system of color mathching and had seen a short videotape demonstrating how this system is used to help clients match the colors of clothes and makeup to their hair and skin colors. To assess the students' understanding of which colors go with which "seasons" -four categories of skin and hair coloration-this instructor used a categorizing Grid. The grid simply consisted of a large rectangle divided into four smaller ones, labeled for the four seasons. students were given a list of twenty-four color names and asked to write them in the appropriate boxes for the seasons they matched.
