Two different font colors in two separate workbooks at the same time?

Hello,

I have two different Excel documents open at the same time in two separate Excel windows (using Excel in Microsoft 365 Enterprise).

I basically have to compare the two documents side by side, and set the font color on one document to be one color (red) for certain items, and a different color (green) on the other document.

Currently, when I change the font color selector on one document, it changes in the second Excel instance as well. This means that every time I go back and forth from left to right, I have to manually switch the color back every single time. I know it's only one extra click, but I have to repeat this many many times each day, every day.

What I would like is for each instance of Excel to be able to remember the font color I've selected for it, so that when I set one window to red and the other to yellow, they both stay the way I set them in that instance. That way I can just click the cell and then the color each time, without having to go through the dropdown color selector as well.

Is this possible?

Thanks for any ideas.

Why not select same color for both documents, then after completion, use Ctrl+F to find the cells with the color and change the color then.

Thanks for the suggestion, but the process uses more than one color and triple-cross-checks with a printed document while I'm comparing the two files. There are also a lot of other colors on the sheet, but one sheet is the previous version of the newer one, so basically I change the new document to match the older one, and then change the older one to show which items have matched. I'm only doing this for my immediate visual feedback though, so keeping them the same color just doesn't work in this particular situation. I was just hoping for a way to basically click one color on one screen, and another on the other screen, but Excel seems to want to match them on both instances. Curiously enough, it doesn't do this with the cell-fill color and actually does let me use a different color per instance (which is why I was hoping there was a way to do this with the font color as well). Thanks again for the suggestion.
