Wood undergoes changes when exposed to direct sunlight (above reference) or
incidental light. One of the changes is a change in color. Others include decreased
film finish adhesion, and some other probably not so good changes.
Walnut becomes pale and washed out, white pine becomes orange-ish
(pumpkin wood), cherry is notorious for getting a "sunburn".
As sort of a rule of thumb, lighter woods darken and darker woods lighten over time.
This site has really well done wood pictures:

One caveat. Displaying my ignorance: I was one of those folks who identified seeds and
wood samples at a USDA lab about 50 years ago. Color of wood was not
ever considered a primary property of wood because of the above. Wood
changes color with age.
The person who put together the site did not mention any standard color reference
about wood, but the pictures have the "correct color". I'd love to learn about
that. And how to know what a correct color is by species.
Question: does anyone know if there is an defacto industry standard for the
color of lumber by species? Could you please provide any links you
might have?
I personally don't think there is one. :(
