How do you make blue buttercream icing?

I've tried adding blue food colouring but because of the yellow of the butter, it always turns out green.

you may need to use a gel or power for your colours.

I have never had any problem with that before... Good Luck,

you need to cream your butter more

yip, beat and beat and beat!! Thats the secret to a good butter icing. Beating it on its own loads them with the icing sugar heaps!!

yep cream your butter more and it will turn white. also use a paste colouring rather than the liquid as they are more intense.
