Why would a rocket change color after it returns from space? I noticed it happens in this video. I list the link to the video below.

Umm... That's soot from the booster flying backwards through its own exhaust plume.  You do know that burning kerosene produces soot, don't you?

The line is too clean to be caused by rocket exhaust.
Might be part of the landing leg deployment mechanism, or at least what's underneath it. Rather than an active hydraulic deployment system, some skin pieces are ejected and the legs (under mechanical pressure) deploy.

For people that can think in more that two dimensions, (most people), the statement makes perfect sense as it absolutely correct.

BEFORE SPACE


AFTER SPACE


It looks like some launch played backwards. I could but humbly hypothesize that two (or more) rockets were launched, then the launch of one of them was recorded backwards as "landing". The rockets might slightly differ but they could forget about that in a hurry or did not care. Exactly like the "spacesuits" etc. etc. etc. in that celebrated NASA movie "For All Mankind" for which I have got a warning from Youtube based on its content. The movie was banned.

By the way, the content of this movie is very similar, so Youtube should probably ban it, too.

But thanks for yet again trying to cover up your shill-chum's mistakes, proving you all act as one.

It looks like some launch played backwards.
Here's for the question of the rocket returning black with a fine band from https://www.reddit.com/r/spacex/wiki/faq/reusability:

Why does half of the Falcon booster look black or dirty after it has landed? Why is the other half still white or clean? What causes this distinctive pattern?
This pattern corresponds to the delineation between the RP-1 tank and the LOX tank and is caused by the interaction of soot and ice/frost. During reentry, the booster travels backwards through the exhaust produced by the 3-engine reentry burn. As a result, the booster flies through a lot of soot. Because the soot produced by the engines doesn't adhere well to ice/frost, but does to the rest of the rocket, it gets deposited much more thoroughly on the warmer parts of the rocket. The LOX, sub-chilled to -340 °F (-207 °C), is stored in a tank above that of the RP-1 fuel, which is chilled to only -6 °F (-21 °C). Because the LOX tank skin is so much colder, significantly more ice/frost forms on the LOX tank than the RP-1 tank. This ice/frost acts somewhat as a protective layer against soot. This produces the clearly demarcated pattern we see between the sooty RP-1 tank area and the much cleaner LOX tank area.


Pretty funny. Rocket landing in reverse:
