The dark parts of the wood are the "late wood" growth rings. The tree grew more slowly during that period and so the wood is denser and more hard.
Those railings appear to be pressure treated lumber. It probably contains metals and other chemicals to prevent decay.
Yeah I didn't even think of that aspect! Treated or kiln dried lumber is some hard stuff to cut. I bet the material I used was just regular untreated pine because it bows like crazy if the humidity changes.
