How to restore default colors in outgoing emails
White background was too harsh on my eyes, so I changed to old "green screen" with green type on black background. This caused some problems with email recipients' readers, and makes for poor print quality (the type is a shadowy gray). I want to restore the original black type on white background. Tried several suggestions, but the green on black keeps coming back. For good measure, please help me also restore the display preferences to the defaults. Release 52.4.0 (32-bit)

You can change what you see to suit you, and what goes out to others in conventional colours.
For your correspondents:
Tools|Options|Composition|General and set the black text and white background for your correspondents.
For your own comfort:
Tools|Options|Display|Formatting|Colours and set the green text on black. I think you'll need to unset "Use system colours" and set "Override the colours…" to "Always".
For the menus and so forth, I think you'll need a theme. Try TT DeepDark.
I think you may have an uneven experience, as certain panes and windows in Thunderbird will still come up with white backgrounds.
And I haven't found a way to ensure printing black on white. In your printer settings look for an option to not print background colours. I think the text will still print in colour, or grey if you can force grayscale. I think I'd take to copying messages to a plain text environment and print from there.
The difficulty is that your OS and its tools are by and large "wysiwyg" but when it comes to printing, you don't want to get what you see.
