Hi,

How do I color dried royal icing roses? With color and water? Color and vodka? I do not have an airbrush. Thanks in advance.

depends ont eh look you are going for. dont use water, it might do funy things to your icing, like dissolve it!
you can paint on colour, by using alcohol like vodka. you can thin down your gel colours, or use a petal, or lustre dust.
if you have the dusts, you can just brush them on dry, which is what most people do i think.
