If you can’t decide on what colors you should have on your wedding cake, just combine some of them and have a rainbow wedding cake. It can actually work if you have a funky wedding theme as well or if you are passionate about the effect. A highly colored cake works just fine for any occasion, including weddings if you make the cake more festive and you tier it. There are several ways in which you can design rainbow wedding cakes, either on the outside of the cake or on the inside. Some might take some time and effort, but in the end, it is worth it.
Colored icing can be used to decorate the rainbow cake in different colors. You can start by frosting the cake using a base coat in a light color, such as light blue or white. Afterwards, put a quarter of a cup of white icing in a plastic bag, one per color and drop food coloring in the bag and mix it up until it is complete. When you have the color intensity you want, snip off the corner of the plastic baggies and draw rainbow stripes on the base coat. Another idea is to use color sugar or coconut. You can put half cup of sugar or coconut flakes in a bowl for each color you want and add drops of food coloring and stir the composition with a spoon. Add as much color as you desire and then frost the cake with a light colored base coat and then press the sugar or coconut on the base before the frosting is dry.
Candies come in rainbow colors. Separate the colors of the candies in bowls by their color and they can become the basis of the rainbow effect you want. Again, use a light color to frost the cake and press the candies in the frosting. You can work the cake in sections and you can use any design you want. If you are skilful, you can design certain characters and flowers out of colored candies, by placing them in specific order.
These were ways to turn the cake as a rainbow on the outside, but the inside can be a delight and a rainbow surprise as well. To make this possible, you need to use gelatin poke. Everything is possible with a little bit of imagination and you can have one of the rainbow wedding cakes as your own.
