I've written a huge complex spreadsheet in Gnumeric, with areas of different background and foreground colors, text and numbers in bold or various colors to indicate meanings. Certain cells ise a diagonal pattern combining the surrounding background color with black - this warns me not to alter those cells when I haven't had my morning coffee.
Big problem is changing just the background color of an area - to do so wipes out boldness, foreground colors and the diagonal-pattern cells. I use "Paste Special" and choose Format to copy-paste colors from one area to another, or make the pattern of bold/normal of several rows match one that's done right.
What I'd like "paste special - just the background colors (but preserve patterns and 2nd colors of backgrounds)" and "paste special - just the text style/fonts" but I've never encountered any such thing. Are the effects I want possible?
