From other reviews I had a feeling that the colours wouldn't be the same as those produced by artificial colouring. The yellow gives a very vibrant colour with little dye, while it takes a lot of the red dye to get a dark red-pink colour. I haven't tried the blue yet, but I guess that using a lot of dye isn't that bad because they expire in about 2-3 months and it's a natural product. I would purchse this product again the next time I need food colouring.
