The term 'Fabric Color' can be solved by the three-letter word 'DYE'. Dyeing is a process used to add color to fabric, which involves immersing the fabric in a DYE bath and then rinsing it. The DYE molecules bond with the fibers of the fabric, resulting in a permanent color change. Different types of dyes are used for different fabrics, such as natural dyes for cotton and synthetic dyes for polyester.
