any workarounds, if they exist.

I insert a text box sized perfectly over the cells not filled with color, then color the interior of the textbox, and set the transparency of the text box way high, so the gray gridlines underneath can show through. You have to go to Page Layout, Gridlines, and check the checkbox for Print, as you do even if you're printing uncolored cells.
