• mixing a second dye solution for a second color in a second mixing system;
• feeding a greige roll of carpet through a dye application system;
• actuating at least one multi-port valve in the dye application system such that the first dye solution is applied to a first portion of the greige roll of carpet as it passes through the dye application system;
• actuating the at least one multi-port valve in the dye application system such that the second dye solution is applied to a second portion of the greige roll of carpet as it passes through the dye application system;
• mixing a third dye solution for a third color in the first mixing system while the second dye solution is being applied;
• purging residue of the first dye solution from the mixing system and at least a portion of the dye application system using the third dye solution;
• and
• actuating the at least one multi-port valve in the dye application system such that the third dye solution is applied to a third portion of the greige roll of carpet as it passes through the dye application system.
