Peach-coloured icing can be used to imitate skin tones, or simply as a cheery tone to add to cakes and cupcakes. You can purchase pretinted icing at stores, but making it at home is easy. Start with a plain white icing, and add as much colour as you see fit. It requires only a bit of extra effort and gives you the added benefit of controlling the shade to your liking.
Add equal parts pink and a bright, lemon yellow colouring to white icing. Icing colouring works best, as regular food colouring will thin the icing. Add icing colouring by dipping clean toothpicks into the colouring, then swirling it into the icing.
Mix the icing thoroughly until the colour is evenly distributed.
Add extra swirls of colouring if the icing is too light. If it is too dark, add extra icing. Mix thoroughly to combine.
Allow the icing to rest for two to three hours before using, as the colours may darken or lighten as they set. Colours darken in buttercream icing, and lighten in boiled and royal icings.
