A method of determining a recipe for providing a desired color and a desired effect, for example, a pearlescent effect, comprises: i. Providing a group of different effect materials, which suitably includes no more than 20 members, for inclusion in the recipe; ii. Selecting an effect from said group which is closest to the desired effect; iii. Directing a match prediction system to use the selected effect material to determine a recipe, wherein the match prediction system determines a recipe based on the selected effect material and color information relating to the color to be matched. A method of preparing a liquid color/effect formulation for addition to plastics is also described.

Color and effects in plastic materials

A part may be manufactured in a desired color from virgin or recycled polymeric material by selection of a color formulation to be used in a first location; relaying color information to a centralized match prediction systemas regards the desired color and other information concerning a polymeric material which is to be made in the desired color. The systemincludes a database and associated software and is able to take the color information and predict how to reproduce the colors using an associated color dispense system. A devicecontrols dispense stationsandwhich may be conveniently situated at customer sites or the like. The dispense stations dispense colors for use.
