This food colour spray from Colour Splash is ideal for adding a burst of black colour to cake decorations. The edible spray is a quick and simple way to add colour to cupcakes, cakes and decorations for a teen birthday or spooky Halloween party. To add an instant burst of colour, shake the can well then hold approx 20-30cm away from the cake or decoration. Spray with the can in an upright position in smooth, circular motions. It is important to keep the can moving whilst spraying to ensure an even coating. .
