coloring the water

[watercatwn6535nd]

Has anyone added food coloring to the plants solution just to see what happens. I was wondering if it would change the color of the fruit. like adding blue to a yellow sqaush might make it green. Or if you added lots of red would it make your tomotoes even red'er. Its getting to that time to start thnking about this year fair and I like to bring a little something differnt. I was going to go with my pineapple this yaer but it just ripened and i think this week its going to become a milk shake. the top of course will be my next plant but not enough time to get it grown to be worthy of the fair.

I was thinking of a potatoe plant, every week chnage out teh solution with a new color. maybe this would give the potatoe different colors inside from when it was grwoing with each color? almost like tree rings? I would enter them as easter egg potatoes.

I'm not insane i'm gardener, after hours and hours in there with them they ask me these questions i have no answers for.
