The invention concerns polymer compositions comprising 20-80 weight percent polycarbonate polymer, 15-40 weight percent filler and 4-20% flame retardant and articles comprising same.

A method for producing a thermoplastic polymer composition comprises the steps of separately providing a thermoplastic polymer and an additive composition and then mixing the thermoplastic polymer and additive composition. The additive composition comprises a clarifying agent and a coloring agent. Another method for producing a thermoplastic polymer composition comprises the steps of separately providing a thermoplastic polymer, a clarifying agent, and a coloring agent and then mixing the thermoplastic polymer, the clarifying agent, and the coloring agent. The coloring agent is present in the composition in an amount to yield a composition exhibiting CIE L*, a*, and b* values falling within a defined color space. An additive composition contains a clarifying agent and a coloring agent. The coloring agent is present in the composition in such an amount that when the additive composition is added to a thermoplastic polymer composition, the thermoplastic polymer composition exhibits CIE L*, a*, and b* values falling within a defined color space.
