You shouldn't. Food coloring does not work the same way that colored paints do.
The color of the food depends on the ingredients used, and sometimes the cooking method. Poaching chicken and fish can make it fairly white. Beef and pork retain their brown/red coloring. If you want to add a white gravy (bouillion, white flour or cornstarch), that will add "white" to the food.
White, or creamy white. Sometimes almost yellow if fresh from cow. And it can be brown or pink or whatever color you want it to be if you add chocolate or strawberries or food coloring.
When you add white to a color, it is called a tint. Tints are lighter, more pastel versions of the original color.
When you are painting, you would add white or another light color.
According to two cake decorators, no. Use a white frosting and color it blue, or a white frosting and airbrush it.
To make white, mix all colors together in equal proportion, such as red, blue, and yellow. Alternatively, you can mix blue and yellow to create green, then add red to lighten the color until it reaches white.
To make a lighter shade, you could add white to the color. Mixing white with any color will create a lighter tint of that color.
You can mix black and white together to create the color gray. The more black you add, the darker the gray will be, and the more white you add, the lighter the gray will be.
