1. A thermoplastic polymer composition comprising:
(a) a thermoplastic polymer;
(b) at least one clarifying agent, wherein the clarifying agent is a compound of Formula (I) below

OG Complex Work Unit Chemistry
where R1 is an n-propyl group, R2, R3, R5, R6, R7, R8, R10, and R11 are each hydrogen, R12 is —CH(OH)CH2OH, and R4 and R9 are each n-propyl groups; and
(c) at least one coloring agent,
wherein the amount of clarifying agent in the thermoplastic polymer composition is from about 50 ppm to about 5,000 ppm based on the total weight of the thermoplastic polymer composition, and the thermoplastic polymer exhibits a blue hue factor (α) of 0.93 to 1.1 and a normalized brightness value (Y′) of 64.0 to 69.6.
