both of which are custom colors that for whatever reason have not persisted in the color palette

Color picker not showing current color
[Solved] I've accidentally modified a pre-defined color!

I have a spreadsheet with over 100K cells, and I'd like to swap a pair of background colors

When you use styles instead of directly setting the cell background color with Format → Cells, then this task is trivial. You just select the two styles and change their background colors. All of the cells which use those styles are immediately changed.

You will continue to struggle with spreadsheets until you learn how to use styles. The best solution is to remove all direct formatting in your entire spreadsheet, then create and apply styles to set the background colors and other formatting attributes like font, alignment, underlining, number format, etc. It is easy to apply a style to a range of cells by selecting them and double-clicking the style in Format → Styles and Formatting. It is better to apply formatting as the last step in creating a spreadsheet.

Would like an extension that can change all cells of a certain background color to another.

You could try RGB which I found immediately by searching the extension website for color. But I don't think this will fix the underlying problem that your spreadsheet does not use styles. I have never installed any extensions from that website.
Get cell color as RGB value in another cell
Set cell color from RGB value in another cell

If this solved your problem please go to your first post use the Edit ☐ button and add [Solved] to the start of the Subject field. Select the green checkmark icon at the same time.
