Change one color without changing the other defaults

[taylor-scott]

I would like to change the background color in the "custom colors" tab. I only want to change the background color, and I do not want any of the other default colors that are loaded in this tab. When I click "background color" and change it, it automatically switches to all of the other colors (pink tab highlight, purple search text, etc.) which I do not want. How can I change a single color while not updating everything else? Is there a list of "firefox default" values that I can use to fix all of the other colors?

Yeah, this issue makes this add-on functionally unusable if you just want to tweak the colors of the system theme.
