PROBLEM TO BE SOLVED: To provide a reactive dye composition that dyes cellulose fiber-containing fiber with good reproducibility, good dye homogeneity, and high fastness, and a dyeing method using the same. SOLUTION: The reactive dye composition containing a reactive dye for red, the reactive dye composition of blue etc., or the like, and the dyeing method using the composition are provided. In the reactive dye for red, a reactive dye whose free acid form is represented by formula (1) (wherein Y<SB POS="POST">1</SB>represents SO<SB POS="POST">2</SB>CH=CH<SB POS="POST">2</SB>or SO<SB POS="POST">2</SB>CH<SB POS="POST">2</SB>CH<SB POS="POST">2</SB>Z and Z represents a group which is eliminated by an alkali) is 10-90 wt.%, and a reactive dye whose free acid form is represented by formula (2) (wherein Y<SB POS="POST">2</SB>and Y<SB POS="POST">3</SB>each independently represents SO<SB POS="POST">2</SB>CH=CH<SB POS="POST">2</SB>or SO<SB POS="POST">2</SB>CH<SB POS="POST">2</SB>CH<SB POS="POST">2</SB>Z and Z represents a group which is eliminated by an alkali) is 10-90 wt.%.
