PROBLEM TO BE SOLVED: To obtain a red reactive dye mixture having excellent fastness and various dyeing properties such as degree of exhaustion, fixation ratio and build-up property and useful for the dyeing of fiber material, etc., by including a combination of specific different kinds of bisazo compounds. SOLUTION: The objective dye mixture contains one or more kinds of fiber- reactive bisazo compounds of formula I [Da is phenyl group optionally having a substituent free from triazine ring, or the like; Ba is a group of formula II or the like; * is a bond connected to azo group; R8 is H or the like; (m1), (n1), (p) and (q) are each 0 or 1; Ua is a group of formula III or the like; R1, R2, R7 and R9 are each H or the like; A1 is a (substituted)phenylene or the like; ** is a bond connected to SO2Ya; X1 and X2 are each a halogeno or the like; Ya is CH=CH2 or the like] or its salt (e.g. the compound of formula IV) and one or more compounds or their salts selected from fiber-reactive bisazo compounds of formula V ((m2) and (n2) are each 0 or 1; R3 and R4 are each same as R1 and R2: X3 is same as X1 and X2; Db and Dc are each same as Da), etc., or their salt.
