Show minimum and maximum of each micronutrient with different colors

One feature that I think most people would love would be to mark each micronutrient (vitamins, minerals...) with a color:

- Grey/black: The daily minimum has not yet been reached.
- Green: Daily minimum has been reached
- Orange: Near to the daily maximum
- Red: The daily maximum has been exceeded.

I think this would help many people to have a better control over their health, since it is difficult to remember the daily minimum and maximum of each micronutrient.
