How to dye acrylic yarn?

[kristalstjean]

I have a bunch of off-white acrylic yarn that I want to use up, but I hate the colour. Anything would be better than this colour. I looked up a few methods and I would really like it if I can use common household products to dye it. However I read up on it and apparently kool aid won't work for acrylic..I briefly scanned over how to dye yarn with coffee or food colouring...would that work? If not, how can I dye this yarn?
