This is green algae?

hello.

I don't know English well. Please understand.

I have a question about green algae.

It has been a 1 month since I set up the fish tank.

I see green paint on the rock and shell. Is this green algae?

That really looks like paint not algae.
Did you use a color filter on the photos?

Thank you for your reply.

No color filter was used. It's original.
The photo was taken using the Galaxy S20 Ultra phone.

Things like green paint are on the rise.
So I was wondering if this was green algae.
Have you never seen green algae like this?
