  Yes i many time used and still using food grade color in handwash dishwash surfactant system and they never get faded in adjusted ph range from 5 to 8 ph o observed mostly if ph raise more then 8 colour changes 
  They last more then 2 years .
  If you want to choose then suggested you to try shampoo based or surfactant based colurs ph  stable. Every company has mention there ph on its datasheet.
  Check before use.

  they certainly can

  whether dishwashing detergent-grade dyes can be used for food is quite another matter

  Thanks @bil7 .

  Yes, I am considering shampoo based surfactants.  Thanks a lot for confirming about food-grade dyes. I have been using them for a while and tested in sunlight too.
