When using edible paint or airbrush paint you will often get the choice of pearl or matt finish. The matt finish will give your a realistic look without the shine that a pearl finish can offer.
A matt paint is ideal if you painting or colouring something that needs to look authentic such as petals and leaves on sugar flowers or skin tones on a cake model. Matt colours will give you a flat finish that is ideal for all sorts of different baking and decorating projects.
