PROBLEM TO BE SOLVED: To obtain a reactive dye composition having excellent level dyeing property, reproducibility, etc., giving low color load on waste water of dyeing process and useful for the dyeing of fiber material, etc., by including a combination of plural dyes selected from specific yellow reactive dyes, specific red reactive dyes, etc. SOLUTION: The objective composition contains two or more dye groups selected from one or more kinds of yellow reactive dyes of formula I (expressed in the form of free acid) [(m1) is 1-3; R1 to R3 are each H or the like; R4 to R6 are each H or the like; U1 and U2 are each a (substituted)phenylene or the like; Y1 is SO2CH=CH2 or the like; Y2 is SO2CH=CH2 or the like] (e.g. the compound of formula II), one or more kinds of red reactive dyes of formula III [R7 to R9 are each H or the like; D is a (substituted)phenyl; A1 is a group of formula IV or the like; * is a bond connected to azo group; R12 is H or the like; (m2), (m3) and (p) are each 0 or 1; E is a group of formula V or the like; R13 is H or the like; U3 is a (substituted)phenylene or the like; **is a bond connected to Y3; Y3 is SO2CH=CH2 or the like; R10 and R11 are each a halogen or the like], etc.
