Vat dyes are less suitable than fibre reactive dyes for the home dyers, as they are difficult to work with they require a reducing agent to solubilize them. The dye is soluble only in its reduced (Micro-disperse) form. The fibre is immersed repeatedly in this oxygen-free dye bath, and then exposed to the air, where upon the water-soluble reduced form changes colour as oxygen turns it to the water-insoluble form. Indigo is an example of this dye class, it changes from yellow, in the dye bath, to green and then blue as the air.
