I have a document prepared with Inkscape that contains bitmap and vector elements:

I want to print it on coloured paper (ivory) with an inkjet printer. Of course, the white background will turn ivory, but I want to preserve the other colours (i.e. that the end-result is as close as possible from what it would be if printed on a white paper).
How to “subtract” the paper colour from the document?
Note: I am fully aware one cannot remove colour, and that the print will be impacted by the paper colour and the ink so the end result will be different. My objective is then to design on the screen what I'd like, and then transform it somehow (i.e. removing the “ivory” contribution in the reds, blue, etc.) so that the end-result won't be too far off. I believe iteration and colour fine tuning will be necessary, but I'd like to limit those as much as possible.
Edit: Here is an (exaggerated) example of what I would like the printed end-result to look like (or not):
