Mati,
I have been orange before! About 2 summers ago,I was eating alot of carrots and sweet potatoes!My palms and face were orange,but as it was summer I think it looked like I had put fake tan on my face with my hands!

It is interesting that it happened the most when you moved into a new house with the chemicals.
I als wonder about if my central (gas) heating could be poisoning me with carbon monoxide,maybe I should get this checked.

Do you take anything to treat hypothyroid?
Also did the yellow/orange go away after a while.
I can live with the colour just as long as I know exactly what it is and why it's happening
