Scene is gray instead of blue and light brown

Hi there!
When I open a new project my scene looks like this. It´s gray instead of light blue with brown. I can drop objects on it.
In game view it looks normal…
Is this normal?
Hope ssomebody can help me
Kind regards! :slight_smile:

In the Scene, you see this button
It has some options you could toggle

There will be “Skybox”
