Thanks, folks, and I appreciate all the input.  It's like here where I'm at, Keith, Cherokee goes from escaped Viking to dark as red river mud due to assimilation.

Again, I appreciate the input.  Some of the technical stuff I don't understand...yet...but I am beginning to see the actual difficulties to some of these problems.  Add to the mix palms of hands, soles of feet, how much sun some areas get vs. how much others get and you wind up with a whole mixed bag.
