I find that sunrise has a more white and blue look to it, while sunset has more of a red and orange look. Is that really what they look like, or is it because of some personal bias, such as comparing sunrise to the darkness just before it and sunset to the bright blue sky?
The page you link says that Golden Hour and Blue Hour occur during both sunrise and sunset, so I’m not sure how that shows what the difference is between sunrise and sunset.
It’s true that it’s mirrored, but the difference is that Golden Hour is after the sun has risen, and before the sun has set. Before sunrise it’s Blue, and after sunset it’s also Blue. Here’s a visualisation:
I figured OP just mentally attributed it to a difference between sunrise and sunset based on their experience so far, so I didn’t mention it initially.
