How to Make a White Rose Blue Using Food Coloring

A simple way to turn white roses a bright color is with food coloring. When the flowers' stems are placed into a vase filled with water and blue food coloring, they will absorb the dye. The vibrant food coloring will infiltrate the flower petals, turning them blue. You can use the dyed flowers as a centerpiece for a celebration, such as a birthday party, wedding reception or baby shower, featuring a blue color scheme.
