1. A method for identifying a best match to a metal deco matte target color and distributing the best match to interested parties, comprising the steps of:
A) i) establishing white and metallic linearization gradation curves for use in a computer implemented environment;
ii) selecting a first candidate color as a match to a metal deco matte target color from a database of metal deco matte ink colors;
B) generating in a computer implemented environment an arrangement of colors comprising the first candidate color and one or more further candidate colors that differ from each other in color increments;
C) printing on a transparent sheet the arrangement of colors to create a digital proof of the plurality of colors and applying a self-adhesive transparent matte film over the colors of the digital proof to create a digital proof with a matte finish;
D) laying the digital proof with a matte finish over a metal substrate to provide a simulation of the application of metal deco colored inks with a matte finish on the metal substrate;
E) selecting a color from among the arrangement of colors on the digital proof as a best match to the metal deco matte target color; and
F) storing color data of the best match to the metal deco matte target color, wherein the color data comprises CIELAB color space information, in a computer storage location for retrieval by other parties.
