Answer 1

If i was you i'd get sick all the time.

Answer 2

I've looked a bit on google, but I couldn't find anything that matched what you said.  I have never heard of teeth changing color during illness!  Very strange indeed.  You should try to take pictures to document your case perhaps.  The closest thing I can think of is from personal experience.  Once when I was sick I died my hair.  The dye didn't work and my hair was a sickly looking color of brown which looked orange under sunlight.  I would look at myself in the mirror and see a flame of orange around my head.  When I got better I still felt sick when I looked at the color orange.

Maybe sickness increases color sensitivity in the eyes.  That is my best guess.
