Polyethylene resin compositions containing mottled colors and a process for their production, includes forming a colored resin by hot melting the resin together with an appropriate color in an extruder. The colored resin is reground to about 35 mesh, and then blended with a flow additive such as zinc stearate, and preferably an anti-static powder. The blended resin is then rotationally molded along with other, different colored resin particles to obtain a final multi-colored, mottled appearance in the molded product. Different color combinations such as granite, green, red, brown, grey, sandstone, etc., can be produced, without the different colors intermixing or bleeding into each other, while still maintaining the integral molded product form.
