From the pictures below you can see that some dyes do separated over time like the blue and dark red dyes. Also the dyes did not change colors will moving. I believe that the Betanin (beetroot red) is a structure of one of the dyes we used in our lab because it looks like the dark red dye on the far right. Dog food manufacturers put artificial food colors in dog food because it might help keep the dog healthy. the two factors that control the distance of the colored dye solution migrate are the negative and positive charges in the gel, and it also helps them move through the gel. the electrical charge causes molecules to move depending on their charge and the gel slows down bigger molecules relative to smaller molecules. they will separate from smallest to biggest with the smallest being farther ahead than the biggest.
