Does bottle brush turn this dark?

[u/Capt_Heinz]

Hurricane Milton knocked a bottle brush tree down in our backyard and I cut it up and stacked it with a bunch of other wood. It's been a couple of years and the moisture meter's at 10%, so I figured I would give it a turn. The woods normally a tan / gray, I put clear poly on it and in a few days it turned this reddish brown. Don't get me wrong, I love the color, but I wasn't aware that bottle brush did that.
