I am attempting to make a cake for my sons birthday in a few weeks. Have the tin and a great recipe for the cake. I was told by a friend that to get bright colours for Bob the Builder I should use Gel colouring. How is this different to the normal ones at the supermarket? Also i looked at spotlight and they only havepowder colouring, would this work or should I order gels. Last question... . if I go gels do i have to get all the different colours or can I get primary colours and mix them. thanks so much :)
