Food4wealth: How do you grow vegetables in different colors?

Some recent how to grow a vegetable Tip on Food 4 Wealth:
Question by Kelsie: How do you grow vegetables in distinct colors?
I’m a mother of a 4 year old, and a 5 year old. Both hate to eat their veggies. I believed if I grew vegetables in distinct colors, they would appear more enjoyable to eat. For example, blue, purple, and red carrots, blue and orange radishes, or yellow and red cucumbers. Just some examples. How can I grow them in various and fun colors? Is it feasible?
@daa thanks! When
