How do you dye red pants?

To dye red pants, start by choosing a fabric dye suitable for the material of the pants, such as fiber-reactive dye for cotton or synthetic dye for polyester. Prepare the dye according to the instructions, typically mixing it with water in a large container. Submerge the pants completely in the dye bath, stirring continuously to ensure even color distribution. After the desired shade is reached, rinse the pants in cold water until the water runs clear, then wash them separately in a washing machine to set the color.
