To fix the opacity of the image, duplicate the image layer about 5 times or more and group all those layers plus the original layer. The result will be a fully opaque image.
The colouring is another issue. You could select the background with the Magic Wand Tool (W), invert the selection, fill a new layer with the required colour, and change the layer ...
You can reset by invoking the menu item:
var myWorkspace = "MyWorkspaceName";
app.applyWorkspace( myWorkspace );
app.menuActions.item( "$ID/Reset " + myWorkspace ).invoke();
alert( e );
Some great info on invoking menu items in Indesign:
Steps to fix:
Step 1 - While still in the "Model" workspace/view, click the double-arrows (facing horizontally) at the top right of the window (just to the left of the word "Edit").
Step 2 - Hold click & drag the blue arrow facing skyward until your model is ABOVE the render plane (anything below position 0 on the graph will be cut off in Render view).
Although there is no way to Export and Import a workspace, there is a way to do it manually.
