Unnatural food colourings are derived from petroleum products, which can make them bad for human health (Allergies, possibly carcinogens, can cause hyperactivity). (There's nothing bad in natural food colourings, unless you happen to be allergic to any of the ingredients).

There are many products used as food coloring. Some are natural. They extracted from plant materials, from animals and some even come from insects farmed for that purpose. Food coloring is also made artificially in a factory from chemicals.
Plain sugar, food coloring, fat, artificial flavor.
snout, mucous green food coloring
Lemon and blue or red or green and mix the lemon with food coloring
All things being equal, color of food coloring will not make a difference. If the ingredients used to make the coloring are different, then there may be a slight difference. This would be a great science experiment.
Food grade wax and a coloring agent and the wick, dye and possibly fragrance.
Buy Jello mix, black food-coloring, and ingredients, and finally make the Jello normally. Before leaving the form, add the coloring.
