I came across this family while looking for something else - I thought it might be of interest, especially as there is a photo of a modern man with blue skin (not with makeup, but through biology).
The Fugate family had a recessive gene which resulted in blue skin. But they were otherwise healthy and lived to old age.

After reading about my favourite Vineans for so many years I have to say this did come as a shock :o)
