A dyeing or printing method of natural and synthetic polyamide fiber materials is characterized by using a blue-dyeing dye mixture, a red-dyeing dye mixture and a yellow-dyeing dye mixture. The dyeing or printing method thereof is capable of giving excellent light resistance, moisture resistance and uniform dyeability to the fiber materials. A dyeing or printing method of natural and synthetic polyamide fiber materials is characterized by using a blue-dyeing dye mixture, a red-dyeing dye mixture and a yellow-dyeing dyes mixture. The blue-dyeing dye mixture(a) contains at least one dye from a chemical formula 1 and at least one dye from a chemical formula 2. In the chemical formulas 1 and 2, R1, R2 and R3 are hydrogen, methyl, methoxy or chlorine individually; R4 is hydrogen or -SO3M; Y1 is vinyl or beta-sulfato ethyl; and M is hydrogen, sodium or potassium. The red-dyeing dye mixture(b) contains at least one dye from a chemical formula 3 and at least one dye from a chemical formula 4. In the chemical formulas 3 and 4, R5 is hydrogen, -SO3M, -COOM, methyl or chlorine; R6 is hydrogen, methyl or methoxy; Y2 and Y3 are vinyl or beta-sulfato ethyl individually; and M is hydrogen, sodium or potassium. The yellow-dyeing dye mixture(c) contains at least one dye from a chemical formula 5 and at least one dye from a chemical formula 6. In the chemical formulas 5 and 6, R7 and R8 are hydrogen, methyl, methoxy or -SO3M; Y4, Y5 and Y6 are vinyl or beta-sulfato ethyl individually; and M is hydrogen, sodium or potassium.
