I love this rainbow cake. The colours blend beautifully. It's not so large that small faces get overwhelmed with one colour. The whole rainbow shines!

This split cake creates the most vibrant rainbow I've used! The colour combination allows for perfect blending to get the look of a full rainbow, and because there are only four colours in the cake it's easier to load and the colours don't get as muddy as the 6-colour rainbow one strokes do
