Perhaps I was too clever, trying to show two methods of painting the
effect. On the watch I did not apply the change to the whole image I
posted. I've changed it now to show the whole face, with correction
applied to the whole image.

I know what you mean about the Select=>Color Range tool. It can be
tricky. This is a different tool that works differently. It is sliders
in the Hue/Saturation Tool and only extends or restricts the color range
and the color feathering range . It cannot select colors outside a
continuous range.

I agree, but it works well for this image. With another, the Hue slider
could be used to get the color in the right range, at least. I haven't
used it enough to know if that will work for most images.

The one I just posted took less than a minute to do, with no individual
area touch-up at all. It may not be quite a 100% solution, but it is
quick and easy.

That's the way for a very large, exhibition print. This technique seems
to me to be good for most other uses.
