Camera background colour in the gameview not changing

I am doing the space shooter tutorial and I am trying to change the default background colour
of the main camera, but whatever colour I give it, it stays brown in the gameview.

Since Im a beginner I figured I must’ve missed something or made a mistake somewhere but I cant seem to figure out what is wrong.

Select your MainCamera gameObject → In the Inspector under “Camera” component change the “Clear Flags” property to Solid Color. Now you can change the background color.
