Rinse your still tied-up t-shirt in cold running water. Rinse until the water runs clear. Untie the t-shirt and continue to rinse in cold water until it runs clear again. Raise the temperature of the water to warm and rinse until the water runs clear. Wash your t-shirt in the washing machine by itself with laundry detergent. Repeat washing until no more loose dye comes out of the shirt. Dry your t-shirt.

 

 

Background:
White light is a mixture of all colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet (ROY G BIV). Molecules absorb some of these wavelengths and reflect others to determine the color they appear. Molecules that combine well with materials and stay fast are useful dyes.
People have used natural dyes throughout history but they were expensive and usually worked poorly. An example of a quality, natural dye is the leaves of the indigo plant. In 1856, a British chemist named Sir William Henry Perkin accidentally discovered chemical dyes in the black tar he prepared attempting to synthesize quinine. His discovery revolutionized the textile industry.
In the simplest dyes, the colored molecules are positive cations. The colored cations are added to materials containing negative anions that help to make the dye hold fast.
