The present invention relates to a coloring resin composition exhibiting pleochroism comprising 100 parts by weight of a transparent thermoplastic resin (A); 0.01 to 0.03 parts by weight of a dye for coloring a resin (B) which is one selected from the group consisting of an azo-based dye (b1), an anthraquinone-based dye (b2), and a methine dye (b3); and 0.1 to 0.3 parts by weight of a functional black dye (C) obtained by mixing an anthraquinone-based dye (c1) and a perinone-based dye (c2). A resin molded article manufactured by the coloring resin composition exhibiting pleochroism of the present invention is characterized by exhibiting different colors of light according to thicknesses although the resin molded article is irradiated with light sources in a single wavelength.
