The Tips And Beds Of My Fingernails Have Turned Orange,

The tips and beds of my fingernails have turned orange, but not the base. I can not think of anything I have done to cause this. The only thing i am doing differently is drinking hibiscus tea. I have been under stress for quite a while, which sometimes causes me to have excema and I've experienced hair loss. I have not noticed any other symptoms. I am female and 57 years old.
