I want to know the answer to the following question:
What type of properties of heartwood and sapwood is often the same even if their colors are very different?
All the background I'm provided with is that "This is produced by deposits in the heartwood of chemical substances, so that a dramatic color difference does not mean a dramatic difference in the mechanical properties of heartwood and sapwood, although there may be a dramatic chemical difference.". Is that enough to answer the question?
Answer: yes
