Add dots of color. Roll fondant into a ball, kneading until it's soft and pliable. Using a toothpick, add dots of icing color or drops of flavor in several spots.
Helpful hint: Tint a small ball or enough fondant to cover a whole cake. As with any icing, tint colors at one time; matching colors later may be difficult. Add just a little of the concentrated icing color at a time, until you arrive at the exact shade you want. If you'd rather not mix color yourself, use pre-tinted fondant in a variety of pastel, primary, neon and natural shades.
Knead color. Knead color or flavor into your fondant ball. We suggest using food-safe gloves when coloring fondant to keep your hands stain-free.
Knead until blended Continue kneading until color is evenly blended; add a little more color or flavor if needed.
Helpful hint: Use the same method to incorporate flavoring or extrats to fondant. Any type of flavoring can be used ? regular food flavors (vanilla, almond, etc.) or candy flavorings. Candy flavorings are very concentrated and should only be added by drops. Flavor the fondant lightly so it does not detract from the flavor of the cake.
Deep colors: When making deep colors, such as black, brown, or red use Wilton paste food colors in larger amounts than normal. It can take as much as 1 oz. paste food color per one cup to obtain deep colors. Deep colors are recommended for accent colors only.
Fading colors: Sunlight or fluorescent light will cause some colors to fade. After the cake is decorated, it is best to keep in a cool room and out of direct light.
Stain removal: All deep colors in nature stain, like blueberries, but none of them are harmful. Paste colors can stain teeth and skin; however, simply washing skin area with soap and warm water will remove color. Bleach can be used on counter tops. Lukewarm water should be used first to spot stained color. Rinse thoroughly, allow to dry. If color is still visible use a commercial cleaner on garment, carpet, upholstery, etc. In the case of a color that has Red 3 as an ingredient use an acid such as vinegar or lemon juice to soak stain first. Proceed with lukewarm water and then allow to dry before using a commercial cleaner.
