yes I have done that many years ago. It was a child's quilt. I didn't want white tone on tone. Dyed it green with just a one pakage of regular rit dye. I came out great. Was a light green with the tone pattern a lighter green. A new tone on tone look. Washed it in the washing machine with dissolved dye (top loader- not sure about the newer type of machines) . Wash as a regular load. Dried it normally. That quilt has kept it's colour well. I would do it again if the occasion arised.
