2. Then click on the new interface and select the "Select-Invert" button.

If the background graphic is not a block, nor a reference, but is composed of basic primitives (including solid 3D entities), you can directly select them, enable the mo command, and change it to 253 in the color column of the pop-up "Properties" dialog box. If it is a block, you need to redefine the block and change the color of the elements in it to 253. If it is a DWG reference, you can first use the REFEDIT command to enter the state of modifying it, and change the color of the object in it to 253 The method is the same as above, and you can use the mo command.

Select it directly and change the color. Or if it's the whole layer, just select the layer and change the color.

Set up layer 0, color (253 or 254) and linear xrefs (reference blocks) into layer 0 and give it a try.
