After piping flower decorations, here are a couple of ways to add an extra touch of color to bring your flowers to life. Use Color Mist to create an airbrushed effect on flowers. Great for producing beautiful gradient colors, Color Mist comes in 11 colors, including gold, silver and pearl for adding a soft shimmer all the way to a metallic look. Pearl Dust (shimmer) and Color Dust (matte) add hints of color to create soft effects on royal icing flowers. Both Pearl Dust and Color Dust are dry powders, so they should only be used on dried royal icing flowers.
