I agree that you will have to buy some different colors and practice
your tone on tone.
Most of the old furniture finishes were just sprayed on, the covered
with some type of lacquer. A favorite of years ago was "provincial
maple" which around here was the color of a Hershey's milk chocolate
bar. Yellow streaks can easily be found in these old finishes as the
resins degrade in the finish and pull slightly away from the wood due
to shrinkage. When purchased, it probably had no fading.
Of course, there was the famous "golden oak" which was used on just
about everything for a while.
Streaking can be caused from a lot of different issues such as
placement in the home, exposure to air flow (go ahead and look at the
grime on that table you put by the return air vent), exposure to
sunlight or a strong lamp, pads or covers left in it, etc.
Be aware that asking "what color is this" over the internet is like
someone asking, "how many fingers am I holding up now?"
