For example, it  works

m := DynamicComposableModel new.
m instantiateModels: #(listModel ListModel ).
m listModel backgroundColorBlock: [ Color blue ].
m listModel displayBlock: [ :it | it printString].

l := ( SpecLayout composed  newRow: #listModel ;     yourself    ).        
                        
m listModel items: (1 to: 10).
m listModel backgroundColorBlock: [:item :index |  Color blue].
m layout: l.
m openWithSpec .

but it does not work

m := DynamicComposableModel new.
m instantiateModels: #(listModel MultiColumnListModel ).
m listModel backgroundColorBlock: [ Color blue ].
m listModel displayBlock: [ :it | { it printString.  it printString} ].

l := ( SpecLayout composed  newRow: #listModel ;     yourself    ).        
                        
m listModel items: (1 to: 10).
m listModel backgroundColorBlock: [:item :index | Color blue].
m layout: l.
m openWithSpec .

About the font: I don't know if this is possible.

For the background color:

This works only for the background of the list cells. If there is no entry
in your listmodel list, the list view is empty as well and there is nothing
to show.

This works:

ListModel new
    items: (1 to: 10);
    backgroundColorBlock: [ :item :index |Color red ];
    openWithSpec.

or with more colors :)

ListModel new
    items: Color registeredColorNames ;
    backgroundColorBlock: [ :item :index | Color named:item];
    openWithSpec.
