Each horizontal row includes a family of colors formulated from a single type of base, i.e., a tint base, a pastel base, a deep base or an accent base. The horizontal rows are preferably arranged in a descending level of lightness, with the lightest pastel colors in horizontal rows at the top and the darkest colors prepared from the accent base in the lowest horizontal row. Methods for producing the color strips and other …
