How do I change the colour of the prompt text in terminal emulators

[Bret Busby]

Hello.

I am running UbuntuMATE 16.04.x amd 19.10, on different computers.

In recent system updates, little green men infested my computers, and,
changed the text in the prompts in the terminal emulators (mate
terminal) to a lime green colour, which, on a white background, is
like having yellow on white.

Also, on my 16.04 system, the spacing has been changed, so it is now
<character><space<character><space><character>, etc.

I have downloaded and installed, using synaptic, every terminal
emulator that I could find, and, they all have this awful green colour
of the text of the prompts.

How do I change the text colour, so that, with a white background, the
text is black, and, in terminal emulators that have a black
background, the text is white?

In the terminal emulator, is Edit -> Preferences, but, that allows the
changing of the font and colour of only the text entered and the
background, but, not the colour of the text of the prompt.

Thank you in anticipation.
