Abstract: Colored yarn poms are color coded according to a six digit coding and are arranged in a particular manner to enable color selection for carpets to be performed by designers, architects and the like without actually examining a sample carpet or a portion of carpet. The color poms are arranged in groups of which one pom defines the base color, and the remaining poms in that group are shaded poms, tint poms and tone poms. The triangular layout provides that the base color bunch is at the apex of a right angled triangle with the shades extending down one of the smaller sides of the triangle and the tints extending down the other side with the tones lying between the shades and the tints. The triangle is an isosceles triangle.
