A method for reducing variation in depth of shade, intensity and hue in space-dyed yarn comprises: injecting at least two liquid dye compositions into selected portions of a package of yarn to produce a yarn having different colors along the length of said yarn, preheating said yarn to a temperature of about 120°-200° F. using microwaves or radiofrequency, and heating said yarn to a temperature sufficient to fix said dye on said yarn.
