Tye dye will be permanent if you use the right dyes. I have done thousands of pieces and used Procion MX dye which is reacts with the fiber in order to become permanent. If you are using Rit or any other household dye you will have fading, although salt not vinegar will help set the dyes.

there is no way to make food color permanent and vibrant on fabric. it is made from organic compounds that are too easily dissolved in water. even if you didn't use detergent it will still wash out. sorry
