An embodiment according to one aspect of the invention is a mixture comprising a thermoplastic resin and pigment microparticles comprising one selected from the group consisting of polycarbonate, acrylonitrile-butadiene-styrene, polybutylene terephthalate, polypropylene, and combinations thereof. To manufacture a marble color molded product molded by injecting Examples according to other aspects of the invention include thermoplastic resins; and pigment microparticles; comprising one selected from the group consisting of polycarbonate, acrylonitrile-butadiene-styrene, polybutylene terephthalate, polypropylene, and combinations thereof. This is a system for evaluating the marble color effect of a marble color molded product, which is an injection molded product of a mixture of the above, and is a light source unit that forms corners with the surface of the molded product to allow light to enter, and the molded product. An image pickup unit that captures the scattered light scattered from the surface, and an image processing section that processes the image captured by the image pickup section in order to derive the boundary of the region where the marble color effect is realized on the surface of the molded product. , The evaluation element derivation unit for deriving the marble color effect evaluation element from the image processed by the image processing unit can be included.
