What is the variables for color changing milk?

In a color-changing milk experiment, the primary variables include the type of milk (whole, skim, or non-dairy), the type of food coloring used, and the addition of dish soap. The temperature of the milk can also be a variable, as warmer milk may affect the reaction. Additionally, the concentration of the food coloring and the amount of dish soap added can influence the intensity and pattern of the color change.
