Recycling Color

When the science of medicine is perfected, all medicine distribution gets controlled, and every person takes a certain color vitamin on a set schedule and time every day.
Whatever color vitamin that day is, has made it so they're only seeing that color until the sun rises then they take their next color as the day resets at sunrise.
Whatever they are wearing, wherever they are going, anything they eat, and etc; they are only able to visualize one accent color each day.
Until a pair meets at a club one night and they both forget to take the next vitamin at the right time the next morning.
Then their next day is overlapped and they are visualizing with two colors. Their curiosity doesn't stop there and they begin to question the science they've always been taught.
Eventually they are perceived as crazy and they get ostracized and sent to live with the other outcasts.
With a bigger number of curious misfits and surviving only on natural resources and without any vitamins they have to grow foods of different colors and learn how to make their own health and wellness recipes. They begin experimenting and exploring with the colors.
Learning how the colors effect which emotions, what happens when someone takes too little or too much of each color, until they learn how to attain a healthy balance of every color and reach enlightenment and plan a way to show everything that's been hidden or unknown to everyone before.
