Some people are so greedy that they can't even choose just one colour sweet so they have to have multi-coloured rainbow sweets and, we have to say, these may well be our favourite type of people! Why have one when you can have them all?! These sweets taste great with their smorgasbord of flavours. Tasty! Rainbow sweets can be great if you're making a rainbow cake but they can also be great just as pretty decorations. Rainbows mean hope in a lot of cultures and, when you're eating rainbow sweets, you're always hoping that there's loads more of them!
