can get many shades of purple out of it depending on how much you use

Bought this to slightly whiten my butter cream. It worked perfectly. Only a drop was needed

Best for my cake decoration

I had to use quite a lot but I managed to get lovely colour out!

Works well for adding colour and can also whiten yellow buttercream in small amounts. Lasts a long time as you only need to use a little. Taste appears neutral. Was easy to clean for me.
