In the replace color dialog, there is a "Hint for window mode" which reads "Click into the image (main window) to set the source color".
However, attempts to do that cause the Replace Color dialog to flash a few times, and a beep.
So either the hint is incorrect, or what it seems to recommend is not exactly what one is supposed to do, or it works in some versions of Windows but not others, or????
I had a line drawing with three colors, and wanted to convert it to bitonal, but one color was below the un-configurable conversion threshold, so I needed to change that color to black so the conversion would preserve it. In passing, it would be nice if the Decrease Color Depth had a threshold setting for bitonal conversion, and a live preview mode as the threshold is adjusted.
I finally used other tools to determine my color number so I could plug them in to the IrfanView dialog. But this shows a limitation in IrfanView 4.37 running on Windows 7.
The way I attempted to pick the color was to click it in the window, while the dialog was active (which failed), and before the dialog was active (which did nothing), and while the "Color" dialog was active (from clicking the Choose button). If there is some other thing I should have done, let me know.
