The invention relates to the technical field of tire rubber materials, in particular to a wear-resistant color-changing-resistant rubber composition for a colored tire tread and a preparation method of the wear-resistant color-changing-resistant rubber composition. Comprising the following raw materials in parts by weight: 140-160 parts of modified white carbon black wet-process natural rubber, 5-10 parts of modified TPE, 3-5 parts of modified EVA, 2-8 parts of zinc oxide, 2-5 parts of stearic acid, 2-6 parts of an anti-aging agent, 3-8 parts of a softening agent, 2-4 parts of an accelerant, 1-4 parts of a vulcanizing agent and 2-6 parts of an activated non-polar metal pigment. And the possibility that the colored tread rubber can be adopted by the camouflage tire is realized.
