A method for matching color of a part to be printed in an additive manufacturing process, includes: (a) blending a color formulation, the color formulation including a thermoplastic polymer and at least one colorant； (b) printing a color chip from the color formulation in an additive manufacturing process； (c) at least one of measuring or observing a color of the color chip； (d) comparing the color of the color chip to a color of a reference, wherein the reference represents a color of the part to be printed in an additive manufacturing process； and (e) repeating steps (a) through (d) by blending a new color formulation that more closely matches the color of the reference until the color of the color chip matches the color of the reference within an acceptable variance. A color chip formed in the color matching process is also described.
