Setting document background color?

[WT1]

When I create a new document, I am given a white background for my new document. How do I create a document with a different color? I'm sure this must be easy, but I am a new user of AP. (longtime user of Photoshop).

Thanks!

What you see when creating a new document is just an empty canvas presented with a matte or a transparent (see Document > Transparent Background)  background.

On the layers panel just add a new pixel layer using the icon at the bottom or via Layer > New layer.

You can fill this layer with a colour to taste, using the Food Fill Tool or via Edit > Fill

New Fill Layer

Is it possible to create the new fill layer a different size (somewhat smaller, and a specific dimension) so I have the appearance of a rectangle within a rectangle, stacked layers in the document? I tried creating document 1 with size 6x4 cm, applied a white fill layer to cover it, then created document 2 with size 4 x 3 cm, applied a black fill layer to cover it, then tried to copy the black layer from document 2 on top of the white layer of document 1. For some reason, the copied black layer from the smaller document completely covered the white layer of the larger document, which is unexpected.
