Ooooooh... I likes redheads.....
I thankfully catch it when it turns chestnut brown, lighter than it's standard deep mahogany, and that keeps it from going redder.
Don't know if I have any pics that show it fully.
This one shows the dark and the light brown.. not sure if it shows it going red.

The above was taken at the open pit quarry at the Pahaquarra coppermines.
To my color-blind eyes, this one shows it fairly well:
