Way back in the last millennium I built a log vacation home.
The log home company seemed to have the goal of selling as many board feet of wood as possible so the partition walls were all clad with 6" tung and groove pine.
All the wood got a coat of polyurethane.
We enjoyed the home for about 12 years and then sold it.
As we loaded up our personal belongs we started to remove wall hangings.
The wood behind the wall hangings was much lighter than the surrounding wood.
I can compare it to an apple that has a four hour old bite and a fresh bite.
At that moment we decided that the wall hangings added too much to the decor to take them away!
