This rainbow rose is fast, easy, and gorgeous! Take a long stemmed white rose and cut the base of it in quadrants. Place each quadrant into a separate glass filled with either yellow, red, purple, or blue food coloring. Make sure you use a generous amount of food coloring for the best results.
You can also do other things with this technique. You could make custom roses for a wedding using wedding colors, or play with your favorite colors. Try using two different colors for an ombre effect, or red white and clear to make a very patriotic rose. Once you start, you just cant stop..
