Funny you should mention that---years ago, in a magazine, I read an
article about diagnosing some conditions through looking at the fingers.
Like "spoon-nails" for anemia...the article mentioned "rainbow nails" as
a sign of internal metabolic dysfunction.  It was vague.  But I have the
rainbow...the pale half-moon, a band of pink, another band of pale & then
deep pink right at the tip.
 
Yes, I do wonder if that's common among us.
