The method of making the thermoplastic polymer composition comprises providing the thermoplastic polymer and the additive composition separately, and then mixing the thermoplastic polymer and the additive composition. The additive composition includes a clearing agent and a colorant. Another method of preparing the thermoplastic polymer composition separately includes providing a thermoplastic polymer, a clearing agent, and a colorant, and then mixing the thermoplastic polymer, the clearing agent, and the colorant. The colorant is present in an amount that provides a composition that exhibits CIE L * , a *, and b * values that are within a defined color space. The additive composition includes a clearing agent and a colorant. The colorant is present in an amount that exhibits CIE L * , a * and b * values where the thermoplastic polymer composition is within a defined color space when the additive composition is added to the thermoplastic polymer composition. |
